but they dont support it either, if not they put grit and oaths out of gcd with that change, and looking how they nerf str builds to the ground and remove healer acc from gears point to other path, its hard to know what devs thinks actually looking at the current state of the game and they choices, some defend this is intenden and others like me think this was a experiment of how this can go and get out of control in the very begining and they try to mitigate the effects of what they do during all the expansion, bcs a total rework can be very expensive and overload the combat team work, compared to 2.x, 3.x get a lot of changes on many jobs with a stats revamp on tanks and healers whit keeping they work creating new mechanics and new dungeons every 3 months.
so i hope we get some new info about what they go to do in the fan fest or at least tease us in some way, in coil the raid desing make the weight of the fight was distributed betwen all 3 roles having boses with want us to get all mitigation posible, boses asking for a lot of heals where they run out of mp (old days when mage ballad was more important), and some but rare heavy dps fights like avatar, alexander put all the weight in the DPS, they put us multiples boms how we need deactivate as we dodging 50cal bullets, at a some extreme point we are not requre to keep our tank stance and healers are looking they belly button so what we do? DPS, our roles are so easy now, dealt high DPS with pretty simple rotations thats all.
so back to the topic and that clemency shield, depend of the game desing, the only way that can work is if that heal shield is enough to take out a healer and solve the dps lose with a 5º dps or healer work being more harder and that make it they save some MP preventing the BRD/MCH have to use MP refress, i dont think save a tank of going to tank stance that rare fight is enough to compensate the PLD dps of all the fight with sacrifice for clemency.
