I would agree that vines is probably stronger, but rupture also deals about 3k damage just in the initial hit without shatter (4.5-5k with) and then ticks from 800-1000 usually... You can cast rupture about 3 times for every second time you cast vines also
1. U can cast 2 ruptures per one vine.
2. Rupture - 3k, not on bosses, lets say 2k + 1k per tick, thats 2k + 3 ticks = 5k. Vines, has double the tick of a rupture, 3 ticks in 15 secs will be 6k.
My suggestion is improve Pummel in 2 ways :
1. Make it hit normally on bosses, I just hit 5255 pummel and on bosses it hits like 1/10 of that.
2. Make Pummel like Double Strike that trees and kelpies in ow have, but different - The mobs have 2 hits that the second acts like DoT and does equal dmg, I think it'll be too OP with pummel, so adding the 2nd hit will have decreased dmg, it'll be x% of the max dmg.
For example, if at lvl 50 pummel will have 5000 dmg, then the lvl 50 will make it 50% of the hit (or make it always 50%) so it'll do 5k then as a dot another 2500. Thats just a suggestion that could be improved, but I think it deserves to be improved, if Quick Strike which should be kinda equal to Pummel hits much harder on bosses, totally free dmg as its truly instant cast, then Pummel's dmg should be increased compared to that (its already is yet not enough IMO).
