I didn't go on hard mode yet, but didn't have this issue on my SMN. On Easy or Medium, in the Dino cluster of people, still saw my effects, Fester worked.*As for credit for participation, there's still the limit on active effects on a target, so I don't even come in there on my main job, Summoner. What is the point of coming Summoner when there's too many effects and none of my DoTs can land and tick? When Fester has no effect because the DoTs didn't take effect? When I have to resort to Painflare spam to get Dreadwyrm Trance? This is also terrible design, and that's why I've stopped playing SMN.
