I can't really see them totally disabling the feature, but what I can see them doing is making the timer a faster ending thing(horribly phrased). Only reasoning in this part is that the feature is supposed to crack down on "spam click" PvPing, but it also hits another angle of issues. Modded clients, more specifically modded clients with "Hacks" installed on them; though this feature won't impact movement "Hacks" much or the other ranges of "Hacks", it will have a large impact upon the all too popular PvP "Hacks". Excluding "Reach" and "Force-field" maybe, but those are rather noticeable ones already. All of the fast-click idea based "Hacks" will do nothing more than minimal damage, hell we'll finally not have someone on our backs about "Hacks" with the loss of a true "spam click to win" system.
On the other side of things...
Good archers are hard to come by, no? Besides, a good archer knows that melee damage is important if an enemy gets too close, we'll be relearning to melee as well(It's not like we can completely avoid melee'ing). As far shields go, well...I'd like to hope that those, who primarily melee, can come up with some of sort new strategy to block arrows. I haven't messed around with the snapshots myself, I really don't plan to anyways, but is it not possible to turn with the shield to block those areas where an arrow could hit? I mean, an arrow doesn't instantly hit a player; that's the only reason arrow strafing is a thing anyways.
Anyways...Update is coming, all of us must adapt in one way or another, no way around adapting to the new environment of PvP that'll be thrown upon us all. Could draw more people towards the PvP community anyways, more to PvP means more challenges to overcome; I'm not sure about you lot, but the only reason I even PvP is for the challenge.
