I will never buy one until I can buy them with CE.
This concept is the whole reason I started playing this game in the first place, and why I've constantly hyped it to all my friends. This was a f2p game that didn't step on the faces of the players that couldn't spend cash themselves, because every CE that gets spent is CE that was ultimately purchased with cash by SOMEONE. Big spenders will be big spenders, and those players that can't afford to be big spenders benefit from them and both ensure the other enjoys the game and keeps playing- and keeps paying. This works very well in EVE Online as well, and I was thrilled to see another game impliment it. Please don't take that away. Don't become just yet another Zynga.
Such rewards would be perfectly fine if they were only cosmetic.
But they are completely new weapons with stats, even if they were USELESS we should still be able to gain access to them somehow.
I don't think it's fair how those of us who can't afford to buy the expansion has to miss out on the opportunity for amazing new items and enemies.
Sure, it can cost a lotta CE, but as long as it's obtainable, that's all I'll ever ask for such a thing.
