The scaling is uttterly stupid.
Solo:
Monster has 2000 hp - easily managable. Also just 1 monster at a time.
Full group:
Monster has 13,000 hp, and 2 spawn at a time - impossible (run out of time due to excessive length it takes to beat em down)
Bosses are insane.. in the 150,000+ hp range, and heal 5000+ per second if regen active... Elementals spawn like crazy, there are 3-4 times the monsters.
Solo: One monster at a time. Elementals dont even spawn so theres no regen, hp is at a manageable 20-30k hp. The rare time an elem does spawn, its fireball does.. 3 damage.
It's insanely broken.
I've solo'd epic25 rushmoor many times succesffully. We got no where in a grp due to the insane hp. Very stupid to discourage grouping this way.
Epic21 is managable, but we shouldnt be forced into soloing or easy mode by broken scaling.
Cut the hp down to 8k, and
DISABLE THE SCALING FOR EPIC.. Implement ACTUAL epic difficulty. EG: Shrines dont reset, scaling doesnt happen, monstrs have maximize, etc, etc.
Got some videos incoming of me soloing epic25 coming up.. I make it look nice and easy... so you can try in a grp, and get crushed! heh.
