The only classes that would be screwed are the new ones which you have introduced without thinking about the most important fact and that is there health pool. Wizzy Wars Taos never had issue on euro, if they have issues on here is because you have made things hit to hard.for exmple orc sourcer -500 from 1 met whats the point? it normally wipes out the sins and archers there and then.
The issue you have now with this change is that classes that dont rely on suns warriors,wizzys and taos in pvp have gained a buff from this. sure a wiz will be in trouble when its shield drops but id rather have this issue then having no shield or hp pool to buff the incoming damage.
next you have crazy hitting bosses. i went on a GK hunt once with GK and a blood mage hitting me i drank 32 suns in the space of 20 seconds. with out the delay i would have died in 3seconds.
Balance the bosses/mobs damage buff there defenses agil or ac amc or even health or respawns, remove sun bundles. you can then balance things a lot easier, Thats how euro worked. i think mir2 forever went down this route as well, removing stacked suns which is a bigger issue then what you have here.
im also positive for the change of 1 second per pot, but id like the mobs balanced in relation to this, esp the lower effective health pool players
I would be surprised if a wizard/taoist wasn't killed from a -500 hit, but sure assassins and archers are squishier than other classes by design.
GK and that entire cave is (at the moment) the highest level cave in game and designed to be difficult and force classes to work together... Working together is the main part I really want to high light because being able to sun pots takes away part of the interaction between players...
Lets take your scenario for example, GK and BM hitting you, without 32 suns you would have died...
Scenario 1 (working alone):
Use 32 suns pots, survive.
Scenario 2 (working together):
Use 20 sun pots, die, have a taoist revive you.
Scenario 3 (Working together, advanced):
Use < 20 sun pots, have a taoist cast EnergyShield on the classes that need it most and revive anyone who dies.
If your group doesn't have classes with the right skill set (and EnergyShield and Resurrection are def dropping), then you are going to find caves that we have designed to require them, more difficult.
I am not saying that there may be some mobs that need looking into (please raise threads if you think there are), I am just trying to highlight that the sun pots shouldn't replace good old fashion team work.
