Wow, I'm a few pages late to reply to this, but I really have to. I just wanted to say that I'm a peaceful person, don't like conflict and berate violence in any form... But I have a really strong urge to punch you in the face right now for being an ****
This might make you stop reading, but I beg you please continue..
My friend introduced me to 40k about 8 years ago when i picked up Eldar because i liked their background, aesthetics and interesting units. I started playing them with the introduction of 5th edition and believe me they were pretty bad back then. They never even got a codex through the 5th edition and were badly outdated. I managed to squeeze a win here and there but was mostly loosing, and you know what? I still had a lot of fun and never complained about anything. That lasted for 6 years until the notorious 6th ed Eldar hit the shelves in 2013. Yes, Eldar got huge buffs all over the place and I was very excited about it. I started winning much more but realized that some of the lists I played really were to strong and my opponents weren't really enjoying the games. When complaints started how serpents were too powerful I dropped them completely (not that I spammed them in the first place but O.K.). To compensate for maneuverability (cause i actually used them as transports) i started using Warp Spiders.. Suddenly they also became unfair - "too fast, uncatchable, OP guns...".
O.K. I drop them too and go for long range firepower and of course War Walkers also became "too cheap for all the firepower they can dish out and their shoot and run back to cover gimmicks."...
And finally there is this one game against the new Space Wolves when I even warned my opponent "Are you sure you're going to move your dreadnaught into assault range of my swooping hawks? They have haywire grenades.." He says "It's ok, he has an inv save..". After the hawks tear the dread apart, they suddenly become OP as well.. And that was just one of many more mistakes he made which caused him to loose.. You know what he told me after the game? "It doesn't matter, I don't feel bad for loosing cause you're playing Eldar and have an overpowered codex...". Most of games I won, felt like undeserved wins because my opponents rarely gave me credit for outsmarting them, punishing their mistakes etc.. It was the codex's fault. (And I truly believe you're one of those players too)
I used to nerf myself into oblivion just to get some recognition for my plays and so both players can have fun and now you're encouraging people to completely decline games with Eldar players... Can you even imagine how that makes me and a lot of other Eldar players feel? Not all of us are playing the game just to win. Some of us play it for fun and you have absolutely no right to take that away from us.
The sad thing is that a lot of people will listen to your advice, cause I've seen similar attitudes on other forums and blogs.
That's really low man.. Really low...
