well, from what i have tested and see today i think the rifblade part is wrongly made.... i was quite surprised as well but i actually deal more domage with my spears than with my blade. so i think the idea behind the riftblade is to keep the ennemy at distance.
- Fork ability allow you to hit 2 targets with your spear and one point into "improved fork"makes you hit 3 target... cooldown is 1.5 sec, that s how i spammed the flamespears.
at level 26 you get the storm burst ability that makes you hit 7 targets for 178 dmg... that mean you spam 3 flame spear (to charge up) and the 4th hit 7 targets... every 4 seconds you hit 7 mobs ... i think it can be very interesting for grindng and for pvp
so i think i ll try a build like this:
