Bumping this. Stopped queueing for BGs for awhile since the snares were so bad, queued tonight, three matches in a row I'm permanently snared in a BG the entire time I'm actually engaging the other team(s). Templar ritual, ice blockade, templar jabs, the list goes on and on.
Jabs is one of the biggest offenders here as far as individual, targeted snares go IMO. A 70% snare on a spammable isn't just a snare, it's a permanent form of cc that forces the templar's target to engage the templar, which effectively takes the person out of the fight. The other solution is to use a gap closer to get to another target, but again, the templar can do the same and you're probably in a ritual anyway, which brings you back to square one. Permanently CCing someone with jabs like this gives everyone else on their team the ability to disengage this 70% snared melee player whenever they're in danger, making a disconnect as easy as just running away. Heroic slash is another big offender too, although the snare is not as strong.
It should not be possible to permanently lock down a player like that, which is why we need diminishing returns/immunity timers on snares. Being CC'd like that for an extended period of time can feel like griefing even when it isn't and will absolutely lead to a more and more toxic pvp environment over time, just as it has in other games before ESO.
The bottom line is that gameplay like this is at best boring, and at worst frustrating enough to stop queueing altogether. It's just not fun at all. Melee without speed buffs in BGs is already a bit slow and sprinting/roll dodging is much more costly in nocp, making the snare meta much more frustrating in BGs than it is in Cyrodiil. I sincerely doubt there is anyone, anywhere, who will tell you that they enjoy being snared the entire time they are actually engaging their opponents, so why is it something that is possible in ESO at all?
I don't mind jabs having the snare (and only on last hit), jabs is clunky as it is and needs to be able to land somehow. Frostblockade and ritual are worse imo.
