I just did a reaver this morning and I have to say I am extremely disapointed with how it was changed. I know this is old news to most, but I personally had only been in one reaver since the change (as a caster), and had been killed early on by my own admitted stupidity hehe. I'm going to try to keep this post civil, but I expect much of my frustration to bleed out into my typing.
Now the old complaint was that casters and clerics were all you needed to beat the raid (and only 1 or 2 of each would do it), while the 9 others would sit on their thumbs and wait for their chests. Melees especially were charitiy cases.
There were many fixes proposed for this, which would have led to a very fun raid using everyone in the party. These included varying the elemental type in the big room, though adding more of them and boosting their power.
Unfortunately whoever changed the reaver raid apparently did everything possible to ruin this quest. First the saves of the elementals seem to have doubled (Even a doubly-enervated elemental would often make a DC 32 Finger of Death save, more than half will waltz through even a spellsung enchantment specced caster's Mind-fogged dancing ball). Second is the elementals in the puzzle room are ALL air elementals. The one room where a melee with a greater elemental bane could actually contribute is now a ping-pong fest (with us as the ball). The only way this quest could be more annoying is to make them all red named (which I expect in the next patch to be honest).
Please bring this quest back to something fun to run every 3 days. Change 33% of the airs into fires, the other 33% into earths. Tell the earth elemetals to forget earthgrabbing a target if it obviously is immune to it. If this was done, then their increased saves wouldnt be a big deal. Alternatively since there is the whole "storm" theme which wouldnt really mesh with fire and earth elementals, you could add other plane of air monsters instead of the hated elementals. Djinni would work, maybe those tripping cats (Bezekira or w/e they are called), some wandering chain lightning/ball lightning/lightning bolt living spells, etc.
