I too know quite a few people who quit playing because of these changes, which is one reason I always bringing up Tactics & Special-Toggling/Spell-casting. all these changes really did was make templates useless/not worth playing, but I have mentioned that many times, and don't feel like going into it much right now, plus it makes me .To be honest every person I've asked that was submerged in pvp they quit because things like the 300 combat point change came in, and the patch before that which cut templates that require all kinds of extra things. like when you could have a fighting skill and no tactics to do specials. Or when you could deathstrike with only ninjitsu. Parry without having to high dex. All these changes cut down what became viable in pvp. Never once did I hear anything about disarm which has been around even before aos.
I also don't hear much about disarm, but apparently someone has , The thing is I don't see so many melee dexers on LS, there are very few, and they do disarm as much as possible, but it could be because Disarm is probably a melee dexers most effective offense aside from Poisoning, so maybe there is nothing wrong with it. it's still annoying for the record...
However, with a Total-Weapon-Re-balance on the way, it could go from "Annoying" to "Overpowered" quick. so hopefully it's tested thoroughly before it goes live.
