Couple things as usual...
"Rake is at best an average dps increase of 25 dps compared to 130 from our bestial empathy pet which we got as a pure upgrade in dodh."
That isn't totally true. First if you are going to talk just average overtime of rake then you have to do the same for BE as well. Unless you are in a situation where you were chaining nukes, casting buffs, etc and still had enough mana left over for BE every time it popped then you don't get that much dps out of BE. In burn situations where you can unload your mana pool it works out pretty well and that's really where the dps of the pet shines because unlike dots it actually works and does a good job of converting mana to damage. However, BE is 525 mana per 18 seconds, that's 175 mana per tick to sustain it. Many beastlords in non-burn situations wind up giving up a nuke or even two depending on what their mana useage is. At that point the dps gain is less than what the BE pet is doing because the mana would otherwise be used for a nuke, it isn't being sustained, etc. BE is great don't get me wrong, but you don't get the spell an constantly do all that extra damage.
Also in "burn" type of situations rake is being used under disc, under BA, etc. I've had a single rake click do over 3k dmg. No it doesn't always do that, but again if we are talking a burst type situation then the return on rake goes up higher than what is sustained during grind-type useage.
"What I don't get is why other bst even think we should compare to other melee in dps. We have many other resources that they do not."
For most it's because those "other resources" are getting smaller and smaller relatively. SA for a raid is blocked by lots, it can be done by one beastlord. Fero has fallen off a ton and in lots of situations it's actually less mana efficent than just nuking. Perfection is a relatively small amount of mana in the pools people have today and uhhhh.... slow? what else do we bring to a raid? We soak damage worse than bards, we have semi-bugged heals at the higher end and although they are decent in a lot of places they don't see a ton of use on raids. Buffs were covered. The warder? uhhh yeah.
I don't mean this to bash beastlords in anyway, but what does a second beastlord bring to a raid other than dps in many situations? SA is covered, slow is seldom(if ever) needed, fero doesn't even get requested much in a lot of guilds I've spoken with, but is ok in some situations. *shrugs* A lot of the bst you see complain about their dps are complaining atleast in part because that is often all we do on raids these days. If beastlords had more "resources" that saw use in a raid I think you would see more beastlords ok, or closer to ok with where the dps stood.
