Admittedly, I may have gotten a bit ragey and non-productive when I first heard about ZOS decision to nerf BE (which I strongly feel was poorly implemented). I'd like to change tone a bit and offer some constructive feedback on what might be a better way to fix the skill.
To begin with, 90% of the complaints about the skill were about people running away with it, not that they were dying to it or that it was too effective in combat. Thus, the answer to BE is to do the following things:
1. Remove the latest nerf entirely. Its dangerously close to a cool down and harms the "use your skills when you want to" promise that is so integral to ZOS's action combat system. If not remove it entirely, see the latter part of #2.
2. Remove the magicka regen penalty for Streak but not Ball of Lightning. Streak is use primarily to fight and in a fight a penalty to your magicka regen hurts you more than it does when you're simply running away. Keeping it for Ball of Lightning makes sense because it makes it a less spammable escape and also because Ball of Lightning has a lingering effect so it makes sense that it might harm your regen (much like Mage Light limits your magicka pool.) Alternatively, remove the magicka regen penalty but keep the subsequent cast penalty only for Ball of Lightning. Having both makes the skill bad. This has the added benefit of encouraging people to use Streak. Ball of Lightning is the current choice for a lot of sorcs and because its lets useful for actual fighting than it is for running away, people are encouraged to use it for running. Making Streak more desirable would solve many of the complaints on its own, since its not nearly as effective of an escape.
3. Make the use of BE remove CC immunity from any source (Immovable, CC break, Auto-immunity, ect.) This would prevent ZOS from harming the skills usefulness in PvE while providing an answer to the players who are unable to counter it and are frustrated by people running away from them. If BE removed CC immunity, you would ALWAYS be able to counter a Sorc with any form of ranged CC (Javelin, Destructive Reach, Obsidian Shard, Petrify, ect.) This would make it insanely easy to counter someone attempting to flee with BE and require a lot more use of LoS and a lot more intelligent play in general for a Sorc to use this to escape. This would be the largest change to BE yet, go further than past changes, and drastically change the way Sorcs play using BE while actually addressing the most common complaint against the skill.
Optional/Additional Changes
4. Increase the damage of Steak. Again, making this morph more desirable than BoL would solve a lot of problems already. Currently, Streak hardly does enough damage and has such a short duration CC that it isn't that desirable from a DPS stand point. Increasing its damage out put would encourage people to pick this morph and use it to fight rather than flee.
5. Decrease the range that one Bolt will take you. Like option 3, this is about reducing the skill cap needed to counter BE. If BE takes you less distance, then it would be easier for other players to Counter you and they'd get less frustrated.
I believe a combination of all or some of these changes would be superior to the most recent nerf for a variety of reasons but, primarily, because they address the problem people were actually complaining about (unlike the current nerf.) The most recent change harshly punished players who use BE in combat for damage and CC while doing very little to stop people who use it primarily to run away (since they can still usually cast it enough times to disengage if they start with a full magicka bar.)
Also, please keep flame out of this thread. I know this particular conversation tends to get heated (I've been guilty of it myself) but I'd like to keep it clean this time. Hopefully, with the help of the mods, we can keep this one constructive. I'm also aware that there are other threads on this topic but I feel that since my suggestions are quite specific and unique, they merit their own thread.
