I main smn and I think it is just fine the way it is. I don't see what all the fuss is about when it comes to smn. I also disagree with people who say that the smn's egi are worthless cause I think they are working as intended. If you don't like smn for how smn is don't play it. Then there's no hard feelings right.
i main as smn as well, and while i do see a few area to improve, one thing that yoshi p did mention from the beginning is that he does not want large pets in the game. Some of the dungeons are in tight places and with the focus being on dodging cones and boxes on the ground, having large pets every where would make this difficult. I dont forsee pets getting any bigger. I do wish too see either ruin go up in damage or something else take its place.
In the end though when the first coil was still a thing, i was pulling second highest dps on turns 4 and 5. yes the damage is all sustain and we have little to no burst and yoshi has said there are changes coming, and from playing dark age of comelot and world of warcraft since the dawn of mmo's there is one rule every one ignores, play what you like and forget "highest dps". you never know what patches bring and class balances always change from patch to patch. Ret pld was lack luster for a few years, then became top dps for a few etc.
