I'm looking forward to the SMN changes, but I do have to question some decision making. Making Fester 200 potency and painflare also 200 potency means there is no decision to be made. Painflare is objectively better as it has the advantage of hitting multiple targets whilst dealing the same potency and having no setup required to cast it. Fester requires dots to be on the target for it to even deal damage and it can deal less than 200 potency if you somehow only have 1 dot up (100 potency) or comically - none (RIP AA stacks). I'm certain that the team will look over the numbers for the potencys of the spells and fix any translation errors in the tooltips as I'm certain fester shouldn't be objectively worse than painflare but reducing the potency on ruin 3 by 25% and making ruin 4 a proc didn't make me very happy either. Bahamut is cool tho, lets not lie.
That said, I am looking forward to see how our single target damage shapes up. Bane was mostly used in dungeons for AOE for me and so the nerf hurts the dungeon clear times. For raids, I've used it on the second set off adds in A9S and spreading the dots from Faust onto refurbisher when his defence buff was up. In A11S it was possible to bane dots from cruise chaser onto 2 lapis and A12S I never even used it (with the 8 adds exploding within seconds). So all in all, its not a MASSIVE loss for the current raid tier. I think when they said they wanted to reduce the discrepancy between top dps players and the average player, they intended for an effect that these current summoner changes will have. I can't hide the fact that I'm disappointed in some of the changes however. For me, it feels like we will be seeing the same meta as we've had in 3.4 and not a single caster making the line up. Its worth keeping in mind that since we only need to keep up 2 dots, that frees up a GCD for a ruin/ruin2/ruin 3 which has a chance to turn into ruin 4. Personally, I don't get the potency nerfs for Ruin 3. I just don't see why it was needed as I believe summoners were in the middle of the pack single target damage wise (tho I don't have any proof of this). I will also miss contagion for longer dots D: But hey, at least we still have Tri-Bind!
As a side note: I propose we make a formal petition to SE to re-name Tri-Disaster to Bi-Disaster. In 5.0, given the current trend of reducing the number of dots, the spell should be aptly named Disaster.
