I wanted to try mirror image build in PvP for same reason I would a summoner damage reduction build, potential immortal but just like summons , the OH% happens to be very low . Well with 3 images, it can accumulate . Although with PTL, Identity, Swap , etc, it can kind of work. Still not that big of damage but then again, there's a way.
Speaking of summons , I remember summon when it worked in arena before, the time mage build from a year ago. Granted it was ages ago but the potential is there . Then immortal build. I mean summon is like Skullshield, Skulldraga , mirror image and minions. It summoner Mythic worked outside of active minions it would be pretty OP but it probably only works with active minions if at all.
Also the Synergy Mythic could be extremely useful. Think barrage build... summon minion, spam the living crap out of your skill and unstoppable. Also in general, 50% MS and APS is quite powerful in a Mythic at PvP. Then there's Summon haste and stuff and if they get affected by Synergy Mythic, even better.
The caveat is the Trickster Set. Mirror images is OK and it's basically a summon dmg% thing at hero points but the Trickster Set not too useful apart from forcing mirror images to come more often. Although it cost a set slot and doesn't seem worth the set slot . Needs one more effect on Trickster or even a Trickster bonus. I mean 20% increased OH per rank isn't so bad of an idea but it may either not be enough or too good.
It's always the underrated stuff that wins. The damage reduction stuff , my builds , etc. They were stuff unheard of or thought not too worth until tried and figured out. There's always a way around things , even if it's more difficult than usual.
Not long ago, people weren't as Tanky in arena either. I mean tankiness was always there but not to the level we have now so it's intense.
The furies even better since they are MH% . That means Identity set , and other things and they have higher base MH% than the OH% minions for eg. One problem is hit frequency but there's a way.
Skulldraga has similar HP to you so the higher HP you get, the more HP it has. Minions and Furies are affected, though not as much. There are ways to get them better though of course. Summons are also great at distractions while you beat the crap out of your A.I . My Skulldraga for eg.
