Shameless plug! Sub to Iron_PatriotMCOC! No!
No offense but get improve your overall gameplay and then make guides on champs after you research them a bit more Blocking way to much, losing prec passive are huge mistakes when using him. His Crit rate is about 23% so he kinda needs it and his block prof 54%Build to near sp2 then apply debuff or build to sp3 and apply debuff periodically. Thing fight could have been an easy solo If you managed the slow debuff. If you know what you’re doing and managing the fight the first prec should last the whole fight. Dashing back pauses the duration of personal passive fury and prec effects by 3 seconds.
use sp2 for +250% increased duration debuff, when it is about to expire use a light attack to refresh it so it does not fall off, use sp1 for precison then sp3 to refresh cartages.
