Coil T4 question. Is this enough?

[TirionCrey]

If everyone has Relic+1 and at least DL...you meet all the DPS requirements needed for T4 easily.

PS: I just read your strategy for the 4th wave. Your problem seems to be that you let the OT grab the spiders AND the Rooks. That's not gonna work. 1 DPS takes one Rook, another DPS takes the 2nd. The other 2 DPS finish off the Dreadnought. The OT takes just the spiders and starts kiting. The MT takes off the rook from one DPS and all DPS focus the one tanked by the DPS, then the one the MT took over.

MT and OT get in position for wave 5 and then you go from there.

PPS: The rook has an ability called "Dox". It's a single target ranged ability that reduced the targets max health. You can Line of Sight it or run out of range(but the range is long so you need a BRD to outrun it cause he is far away anyway). If the tank grabs all the spiders and the Rooks he can't avoid Dox cause one of them is prolly gonna hit him at any time which is prolly why he dies, cause his max health gets so low that there is no way you can keep him alive.
