I'm playing against Eldars recently (for the rank 5 in all factions). I think Eldars are in a good spot right now (in range fights). Of course I think the Sorc is better than the Warlock as it can do everything better (heal and melee). The TLSC + Shurican spam is really powerful. The SH are really a pain, they can move really fast to safe sniping spots and harass. Eldars lack lascan for maps like Harkus and some efficiency in melee (choice of weapons tier).
You can't tell us to shut up in our own forums section. If you want to whine, then fuck off to your own section. If you want a discussion, then we are going to have an opinion. My opinion is that Eldar are actually feeling fine this patch, for the most part. Orks, however, still need some stuff before they can be fully competitive.
Tell you what why don't you make an Eldar character and then post a win of a few hundred kills if Eldar are so easy and so powerful. Until then posts like this are being put to the sword. Do not start a new one.
