pyro1 u waste a rank late game.
pyro2 gets you easily to lvl 120 or so then starts to fall off
pyro3 gets you to lvl 200 then starts to fall off
you need linker 1/2 100% if u go pyro 3
remember link1 5 link, link2 8 link
so link2 gives max of .375 or 37.5% more dps if u want that
for the nerf, what hurts is not the CD but the bind duration
it takes time to tick the fireball, and u are pretty close to the mob when u bind it, so when they move u take a bunch of dmg, as you will have to focus more on con instead of int.
also, i think mobs that are linked, but not directly hit by fireball take less dmg than those that are linked and directly hit by fireball. there is still some multiplier going on. so, im just afraid of killing some linked mobs, breaking the link, then the rest of the mobs are alive, you’re skills on CD= inefficient mobbing.
at link2 you have 3 sec of bind, which is about only 5-6 fireball ticks.
