Spoiler:
So, it's better to jump around, cauterize spam (which you can't, with 5s cd, also, it would remove just the weak dot, not the crucial ele debuff or WS), detaunt whoever places a dot on you, hide behind trees and pop flee whenever magus pet throw ball at you?
If you look closely the guy was at more then 100ft, so detaunt/silence doesn't cut it, also, you don't know if he had immunities or not as it isn't shown. I was bombed by the second magus in the back, not the one that I targeted.
Or, just or, put a trust in 4 of healers you have behind and try to push enemy lines to regain control over the sc, do the job that dps should. It's easy to criticise, especially when vid was slowed down to the max and you have the illusion of all the time in the world.
I just cut this clip in order to provide that magus burst can be incredible, same as bw/sorcs and at the same time its not telegraphed or cleansed that easily.
Cleanse 2 BW/Sorc important dots that they do - they're done, cleanse 2 fluff dots of magus that are being cast in order to hide important ones, and he'll still bring you down when not using detaunt, as you pretty much can't break los when BoC is already being casted.
It wasn't done to show that magus is OP or my skillplay was awesome, as I was dicking around solo in sc with some weird build.
Anyway, casters as a whole are in a pretty dark place now.
