eh, idk bout you, but i play WL and WL is an underdog rn, didnt encounter someone who did behave abnormal yet.
some classes have a oneshot skill, like Warden has Divine strike that can if properly aimed nearly oneshot you.
Bns Buddy has nothing to do with XML edits, and they actually tell you to NOT use any XML edits. BnS Buddy actually helps to make the game more playable and to get more performance out of your game, by the command -useallcores and the Core affinity and to be able to remove animations / particle effects to make your Game run smoother.
Trust me a Raid with 15 FPS is Hell.
Yes there are Classes that are annoying, like Blademaster who have like 1000 CCs and can block everything and obviously KFM as Fire KFM is a guarantied loss for me, no matter how hard i try to outplay them.
For some classes the Aircombo is an essential part of their damaging of players, else their skills arent as effective, also you cant counter anything while in air, so yes obviously people will try to aircombo you.
Either you gitgud in PvP or you dont, but complaining like this on the forums wont help you, it'll just make you the butt of the joke.
also i havent really encountered someone that attacked me while i had the load in screen, then again my PC is fast and my internet is good.
Thats the Balancing for you.
