Well, the new Battle Robits from the Admech will do a better job at laying down Str 6 wounds at nearly the same point cost so I'm not sure where to file your complaint.
Guardians can be avoided easily, as can the hawks (seriously, you're complaining about a unit of T3, 4+ save dudes?)
Have you actually played a game against the new Eldar yet? I've played a game against my buddy who was using blood angels for the first time in his life and he came within a hairs-width of tabling me. If it wasn't for a lucky inv save on my war walker, his furioso would have just careened through my lines and tabled me on turn 5. Not to mention the fact that his damn assault marines with 2x flamers and a sanguinary priest didn't finally die until my last round of shooting while they racked up quite the impressive mount of dead guardians.
Yes Eldar are powerful. They should be. They die SUPER EASILY* though.
