There have been... so many changes to abilities over ESO's lifespan, it's crazy that I can only really think of three things I legitimately feel the game is lesser without. That said, there are some things that used to be that no longer are, that I miss. Also, this isn't to say that there aren't a million other considerations to be made with these things. These are just my personal thoughts and preferences... and I apologize if I get a bit rambly.
1. I miss being able to use invisibility as a Nightblade tank, or any non-DPS Nightblade, really, without sacrificing a significant part of my build. I really enjoyed being able to cloak for utility, for dealing with PVM content, going on NPC murder sprees in town, stealthing through tricky areas, or even in PVP just as a defensive tool rather than an offensive one. The main issue is that cloak morphs either to focus on DPS burst, or loses its invisibility effect. Now don't get me wrong - I really like the tank effects of the defensive morph - I'm just sad I have to give up invisibility for it. Even when I don't particularly need the health recovery, it's hard to justify the DPS focused morph as any non-DPS build.
2. I miss being able to stack heal-over-time abilities, namely grand healing/healing springs (I think I got those morph names right...), but others as well. Especially for Nightblade, which lacks any really good AOE heals, it was really cool to have an AOE heal that would ramp up over time, instead of having to scramble to send heals to teammates one at a time. Maybe even just having options for AOE heals that don't rely on using a specific class would be nice, y'know?
3. I miss having a magicka tank weapon. Now I don't need it to be the frost staff specifically (though I think it fits quite well), just some sort of tanking kit that uses magicka (just like it would be cool for stamina healers to be a thing). Specifically though, I miss the frost staff heavy being a taunt. There are so few ways to taunt in this game, that one extra choice opened up a lot of options in a build. Conversely, taking that away completely shut off a whole category of builds. It was really cool to have a staff that was effectively in a new category, like resto staves are, and getting rid of those things that make destro staves unique is in some ways kind of like taking away that category, if that makes sense.
Now, I do understand why these were taken away, at least generally (I think) - PVP balancing and Nightblade tanks wanting a powerful tool for their kit, server data stuff and general OPness, and players who either wanted their original frost staves back for flavor or players who taunted enemies away from tanks in dungeons because they didn't know how frost staves worked, respectively. Each one of these, however, straight up killed really fun unique builds I made. Overall, these kinds of changes I think took away a lot of uniqueness and utility and versatility from the game. And, to be honest, a lot of these kinds of changes reinforce meta builds and get rid of creative ways to play - and I thought was the whole philosophy of Elder Scrolls games was to make your own unique character and play the way you want, not make the same thing that everyone else is making because that's "what's good".
I mean I fully get that, at least these three things, will probably never get reverted. I mostly just want to let the devs know ('cuz honestly I've never known a more community-focused team than ESO's, so hey maybe my feedback will mean something), and I want to see if anyone out there agrees with me, or has their own things they miss for some reason other than that it was powerful. Any creative solutions might be fun to hear too. Especially with all the other changes the game is constantly undergoing... well, what do y'all think?
