I worried about SCH whilst I was levelling to 70 but the job changes helped alleviate a lot of my concerns. So did getting better gear and learning the dungeons/raids. For me, SCH is all about planning ahead, and obviously that gets easier and easier the more times you run something. I currently have zero problems even with big trash pulls. But - and it's a big BUT - i generally run everything with a tank friend (DRK) whom I trust to do the right tank-y things and we're also generally on voice chat so i know if he's intending on pulling the whole floor. In raids I generally go with other FC members so we make up at least half the party. All of the above make SCH's planning ahead ethos much easier to handle. It's very possible that the issues you're having, OP, are because your tanks aren't fully geared yet/aren't using CDs; you aren't fully geared yet; and you haven't yet learned the fights thoroughly. The first Deltascape V.1 I ran i was shrieking 'OMG, I can't heal this' when Charybdis started up, but now i have zero problems because i know it's coming
