I dont farm campaign for gear and havent for a long time. I dont keep or use white or green artifacts, any i may still have was from a long time ago. Wurlim is one of the few i never regeared as i dont use him much. Stag knight has most of his original gear but hes being used in everything without needing a change so i dont fix whats already working just fine.
Im farming for speed, life steal, perception, stun, regen, shield, etc. I just cleared dragon 25 on auto, first attempt at 25 too!
My arena team needs more speed and more useful substats on gear. I use seer, stag knight, mausoleum mage and miscreated monster. Seer uses up to 30 or so buffs to nuke the other team and i have them going in order properly, they just need better gear that ive been trying to farm.
The only thing i hate about arena is my champs' gear. I was in gold 4 awhile but then i slowly slid down to silver 4 and i didnt change anything to cause that so im perplexed why i cant get back into gold.
Its a gear drop issue which i have zero influence over. Unless they change things on drops, im probably not going to get back into gold for awhile.
