Resolution and Double attack

[Arcon]

I have gotten a 6 hit resolution showing it can proc on 2 hits but it may be the old only on first 2 hits thing.

Resolution is five-hit, so six-hit means you only got one DA swing in (assuming no others missed). And since eight hits is the maximum, it would be really hard to test unless that case with full TP really occurs (and you have to take Store TP on multihits into account, a mistake I made a while ago). You'd have to do a pretty large sample if you wanna determine the average, because DA can only proc on three hits (for the eight hit limit), as opposed to the two hits it would normally occur on. Also remember to consider any TA gear/traits.
