I have heard of a few games rendering the animations in such a way and I can see how this would affect PvP.
We have tried to read and have heard there are some concerns with game balance, but the forums at THQ*ICE is hard to read over the last couple months with the community being so vocally upset. So many threads that are well hard for us to sort through to find the community issues.
Personally, I feel as if Barunson is making their changes based more on the PvE aspect of the game, rather than the PvP aspect. As a result, some classes have grown exceptionally in PvE and PvP (ie. warrior classes due to various skill changes and a 1.5x boost in attack power on their weapons). The reason why their weapon attacks were boosted is that the warrior classes were lacking in the PvE aspect. Meanwhile, characters that didn't lack so much in the PvE department had their weapon attacks reduced. As a result, this makes it even more difficult to defeat players who are stacked with both health and defense, as damage becomes mediocre, and with healing from mages, it easily becomes nearly impossible to defeat one of these players unless there are multiple people locking them in one place with all their skills. In addition, due to this, I believe the ninja class has slightly deteriorated in that Barunson is changing their skills and basically rendering the air combo (not the actual aerial combo skill) useless and outdated, forcing us to resort to a ground combo based on no player skill at all. In other words, the style of game play for some classes has been changed as well, and I also feel that this is a negative change as opposed to positive.
Now, of course, it would be quite difficult to work out a solution that works for both PvE and PvP, but that is even more reason why such changes should not be made before thorough testing by the
player base. The fact remains that the players are always the ones who are generally more familiar with what changes should and should not be made, with an exception of possible class bias towards the class that they chose. In short, ideally, I would like for Gravity to look more into these issues and try to work out something better with Barunson, but that probably isn't possible at this point. It is something worth considering in the future, though, as many players, myself included, feel that the changes Barunson puts forward are not necessarily all positive changes.
