adjust cast timers - weight of the land needs to be adjusted by .5 to 1 second to account for latency and control issues. On a controller, you have to move your finger back to the stick and not only that, but move in perfect direction. On a KB, as a healer you have to move your fingers from the F keys or number keys to get back to the movement keys. This means that the only way to avoid weight of the land is knowing when it comes and already running when it is being put down.

reduce heart HP - Limit break lv3 is required, therefore this is very restrictive on what you can do from phases 1-3. Phase 1 requires auto-attack and nothing else. Phases 2-3 require slow dps in order to build the limit necessary to reach level 3. High dps literally does not matter from phase 1-3 and is actually a detriment (since limit cannot be built in time). Heart HP needs to be reduced so that it can be viable with a level 1 or 2 limit break (preferably 2). I would say about 15-20% reduction.
