Doesn't make much difference, mobs and bosses die to fast in both cases. Rofl has not enough hp/def for more than two well equiped dps. Big pulls die instantly & mobs don't live much longer. We had two addphases on last one, so yeah 0-1 with more ppl, not so much impact. In fact, I'm quite certain wl/Wd will be even stronger if fights last longer in the future.
It makes a hell of a difference. If you have more damage dealers (especially good ones) factors like pacing (and in turn movement speed or range) directly translate to damage dealt by the individuals. Those are not very important when damage dealers needn't compete with each other. The result (dead monsters) is the same, the way (2dds + many supps vs many damage dealers) is very different.
In fact we had 2 range dps and a WL/M. Nothing more. So it doesnt make a difference for our comparison. In fact, Scout would be even a bit more weaker than WL/wrd, because the Scout has casts/Channels, which he cannot bring to target with more dps. The WL/wrd would in this situation even more stronger
Kind regards
