ESO dungeons are some of the best dungeons I've ever played in any MMO, and the Dungeon Finder is a great way to quickly join a group and have this experience without the grueling experience of finding a group manually. For those with guilds and enough online friends to avoid PUGs (pick-up groups), the dungeon finder is a simple and expedient way to not only run dungeons, but receive extra experience and rewards from the Random Dungeon option, but for those without this, it can be a flip of a coin as to whether you will enjoy yourself. I don't mind grouping with good players who want the typical party and dungeon experience, with a tank/healer/dps and strategically combating through the bosses, but I really do resent the Dungeon Finder when I am grouped with a high-CP, uber-geared player who wants to ignore the group dynamic and just farm the dungeon, whether for personal loot or to speed-level a friend's character. Time and time again, I've found myself in a group where the whole party isn't even instanced in and one player has already managed to solo the first boss by him/herself. Some players might shrug and think, "Easy experience, easy loot!" but it is ultimately game-ruining, especially when I am playing with friends who are lower-level or - more importantly - newer to the game, who don't really understand the dungeons yet.
I gave it some thought and I feel a few changes are needed to really bring the Dungeon Finder into a good place that will benefit all players. Here are some suggestions:
1. Disable Champion Points for Dungeon Finder
This one will probably be the most unpopular, but I think it is needed. The Dungeon Finder is primarily useful for players who can't form their own groups. Players with high CP who want to use those points in dungeons are still 100% capable of forming their own groups and joining instances from the world map. If you'd rather use the Dungeon Finder for ease of use, you should be willing to lose your CP points for one instance so you are closer to the abilities of your group. This retains the enjoyable and challenging nature of the content itself, prevents other players' experiences from being ruined by rude high-levels, and also brings a level of skill into the mix.
2. Allow Level Cap/Slider Option
In AvA, there are campaigns that say "players under level 50" and I think that should be applied to Dungeon Finder. Lower level players should have the option of deciding if they group with people 50+, and I think it'd really be a good idea to also allow an alternative two options to "group with any level" and "group with only 50+." OR... Just implement a slider in the Dungeon Finder that says what level variant you'd be willing to accept. For example, "Only group with players within X levels of myself." i.e. You are level 20, you select a variant of 10 levels, meaning players between 10 and 30 would be grouped with you. And of course if you are grouped with a high-level friend, some of those options would be grayed out.
3. Heavily Update the Dungeon Finder Algorithms
Also, this could perhaps be a simple matter of reprogramming the Dungeon Finder. If a player is noticed by the algorithm to be completing dungeons outside the range of his/her party members, or is recording doing seemingly all the work, they will be automatically grouped with other players of the same nature. If a 600+CP player is grouped with a level 20 player, maybe they are grouped with similar makeups i.e. another 600+CP player with their level 20 groupie. Patch the game to record some small details and stats about your dungeon running and truly renovate the Dungeon Finder so that it intelligently groups you with like-minded players.
4. OR Simply Disable Champion Points for the Random Dungeon Dailies
If all fails, a simple solution really might just be to disable CP for the daily dungeon quests. After all, why should ESO reward players who want to grind loot and EXP with more loot and EXP? Elder Scrolls is not a grind game. It's a story game. That's why all NPCs are voice-acted. That's why the lore is so rich and deep. That's why each dungeon has a quest and story to it. If it was about grinding, don't you think the game would tailor itself more to grinding instead of story? So, why reward these players who just want to grind-grind-grind, all the expense of other players, particularly those who are lower-level and likely newer players or at least players who aren't hugely regular? If they want to grind a dungeon, let them manually join them to get their CP points, but even then, I revert to #1, where if you really want to use the Dungeon Finder, you should be okay with your CP being disabled.
Dungeon finders are generally dangerous and risky tools in MMOs. They install an element of grinding into the game, and this is not always what that game needs. Why would I want to quest or explore Delves or any of those other game features if leveling requires running daily random dungeons over and over. Dungeons should be extensions of the Elder Scrolls experience, with challenge, strategy, story, and teamwork as key elements. The Dungeon Finder in its current state is dangerous to ESO as a game, because it's reducing the depth and richness of the game as as whole, and should definitely be changed in ways that may be drastic to some of these grinding players, but ultimately beneficial to the game itself.
