As far as problem 1 goes there is definitely some fine tuning and learning involved in both LOS and range when healing. Running instances like UD Strat was helpful for that because of all the corners in the city. Range is tricky. Thats why I often stand too close to the tank and target for my own good (of course it also provides a good view ). I cant speak too much to the damage being done by the dogs but Golemagg was hitting for about what he usually does. I think the main roblem was (shameless plugg) the lack of priests, ideally I would like to see at least six of us in an MC raid where you have multiple tanks tanking multiple targets, I know we cant always cover that and so we need to be flexible....an adequate amount of healers is as important as an adequate amount of tanks and dps. Unfortunately, druids and shaman, while they are good healers, have a hard time filling in a priest role.
In my opinion, I would like to see two priests for Golemagg and two priests for each doggie, just like we have two tanks for Golemagg so they can switch out. Six priests would also allow for a priest for every tank on domo and his buddies. Druids and shaman are a godsend to cover our arses and God knows I love my crack (a.k.a. innervate), however, it is difficult to use them as primary healers for a tank. Unfortunately, I have little to offer in the way of advice in the case of a lack of priests as described above. Hopefully, we can attract a few more in the future.
This week I suggest we pay close attention to our healing, especially things like healing rotations so we can handle the oom situations more effectively as Benim and I have discussed, and if a healer thinks they are out of LOS or range, they probably are. Thankfully, range is straigtforward since you can gauge that by looking at your hotbar.
Most importantly, lets kick his arse!!
