I play both Wiz2 Kino1 and Wiz1 Kino2. My personal experience finds that the latter build needs good fillers thanks to some useful skills have been rendered unusable due to cast time interruptibility. On the contrary, with Wiz2, you can use Snow rolling, Rune of destruction, or casting Rune of ice mid battle without the fear for being interrupted.
Well if you go Wiz1 Kino2, I suggest you consider going for Sage. I find that the number of walls hit by PP will not be that much than 9-11 slots, due to the area of effect of PP, with Sage casting duplication on the wall however, that number could go to 14-16. Beside, Sage has a few more attack skill to fill CD which do not require casting time (there’s a discussion right now about the usability of Sage C2 skill, but I don’t think it would be much of a matter since all we need from that skill is not damage but the pulling effect).
Kino2 Stun and Magnetic force have some utility in PvP. Though I would say the same for Snow rolling but with less confidence.
So if you wanna play Wiz1 Kino2, I suggest Sage as your higher ranks.
For Wiz2 Kino1, which your play style won’t require that many fillers, then I would go for Enchanter. Enchanter has a lightening buff for Icewall-PP that could add the damage of each bullet for about 500 unit. Base on my experience, you won’t even need RC with this buff everything molten down like a cake lol. Besides, with lightening hand, your life on the field will be much much much better.
So here is my verdict:
For pvp and burst Icewall-PP damage, Wiz1 Kino2 Cryo3 RC1 Sage 2. If long CD does not annoy you in the fields.
For pve,Wiz2 Kino1 Cryo3 RC1 Enchanter2.
But who knows for the future?
