Spread Shot 5100 base 3 times is stronger 
When you played the last time solo ? You shouldn’t just evaluate skills for what they are doing for you, but also for your party. I’ve 3 Wizzys (263, 253 and 231) and i can tell you, that Falcon attack in PvP is the most annoying ■■■■ ever 
Im also curious about the synergy of Koochaksal and Circling (If there is some). The skill shots homing missles, like Magic Missles from Wi3. Ever seen what happens if you fire MM into Mobs w/o AoE Def ratio?
If there isn’t any synergy, you still got that nice AoE debuff and that little bit CC of your Falcon
Overall, i think it will be solid cuz:
All the stuff just buffs my damage for Mergen (Steady Aim, Swift Step) + Utility (Hide, Silence, KnockBack, Bleed, Armor Penetration). The rest of the skills are just for leveling up :). As for filler during Mergens CD, i gonna use Bodkin Point and Cross Fire.
