The thing is, thinking about it now, the amount of people polled are the smallest fraction of the actual player base. I don't think that we can accurately extrapolate anything beyond the few people who are even actually aware of what Darth Hater is.
I really wish this game had the same representation that WoW gets with MMO Champion. When I was playing WoW I would check that site every day. With Darth Hater, I just don't expect much - which is really too bad. I know this game and the people that play would benefit greatly from a website that brings the same level of content and information that MMO Champion brings.
It would be a small sampling of course and probably be just those who have been already playing the game. But I just can't see the real results being far different, everything seems in line with what I imagine would be the split.
Never see free players doing hard modes and doubt many are running around doing ops. Doesn't help that doing either of those activities is pointless without first buying the artifact gear unlock which is pretty pricey. Also the currency limits placed on f2p players further makes buying the weekly passes pointless since they can not earn enough coms for the gear they need, while the vendors also charge the f2p more for the gear, which they had to buy the artifact quality gear unlock for. Why bother raiding when that way you can not properly gear up for the raids since the hurdles pretty much stop you? You cant realistically play for free and do end game content for cheap so why would people bother? Premium players still deal with these currency caps and increased vendor prices so the whole thing about playing your way doesn't really work. Anyone who wants to take part in endgame play has to basically sub or get out, which in the long term does not sound like a good solution as free players taper off instead of progressing into the end game and helping to further grow that part of the game.
If it turns out to be true and the weekly passes are just not being bought, it would be in their best interest to just give them out to the free or at least premium players or with greatly increased limits to let them be able to participate on a semi regular basis. Would go long way to build up good will towards the game when there is so much negativity to it and how the f2p has been handled.
