Anet please fix the balance in your game. Things like this should not be possible under ANY circumstance. Getting critical hit for 10 k damage by an 1500 range AUTOATTACK is unaccaptable. Getting hit for 6 k damage by a 1200 RANGE CROWD CONTROL ABILITY is unacceptable.
Regardless of the gamemode. Regardless of the cirumstance. Its a ranged weapon, requiring 0 skill or coordination, simple key spaming. Damage numbers like this might be acceptable if the base healthpool is 200k.
This is just a isolated sample of the many cases of balance that are wrong in the game. Warriors critting for 6 k damage with a gapcloser and stun skill. Warriors critting for 6 k damage with a EVADE skill. Thief having a 4 SECOND EVADE THAT DEALS DAMAGE AND HAS NO COUNTERPLAY. Thiefs hitting you for 12 k damage out of stealth, with no counterplay. Engies with a 2 second CD gapcloser that crits for 5 k damage while spilling boons. Multiple, overlapping skilleffects and skills that are so overtuned, both in damage and effect. Your philosophy always where to not add mechanics that are unfun to play against. Why do these things exist? Why do they even get buffed? Why do classes like thief and mesmer exist in its current state? Its not fun to fight against a class that can disengage at will, or vs a class that has such a high evade / damage immunity uptime with NO counterplay.
Balance like this is a disgrace to the entire game you built, it nullifies the great quick and very fluid combat system you crafted. It ruins all the combat mechanics you created and added. The powercreep simply devalues active play, it devalues strategy, tactics and timing in exchange for powercreep.
