It should be available to all regardless if you vip or not. It should not be a VIP only perk. I have read multiple threads on this and heard all arguments and can agree with both sides. VIPs that pay for subs and buy extra hair dye, armor kits, xp pots, and etc spend just as much if not more than premiums that own all content and make similar extra purchases. Therefore end up being equal in monetary value. Of course, there are the other extremes where VIPs only buy subs and nothing more and premiums that buy only the smallest point pack. How to make this even out seems to be the problem. I have posted my solution in a couple threads but am sure it will go unnoticed by all the "who has a bigger e-peen" based on who spent more.
MY SUGGESTION:
It is rather simple if you ask me. Let premiums that own all packs and thus all quests open said quests on all difficulties. Once a new pack is introduced they lose that perk until they purchase the new pack. Sort of like a completionist for owning packs.
VIP can still feel special over the premiums that spend little money. Whereas premiums that spend a lot of money to own all the content get similar perk. To the VIPs saying that premiums can favor farm to buy packs or get a guildie/friend to open elite are naive. We are premium and made the purchases because we do not want to waste our time favor farming for a measly 25 TP for every hour, if you get it that fast. Just not an enjoyable way to play that game at all. To the other suggestion, of getting a VIP to open elite for us is equally ludicrous. Most people do not want to beg for people to help them and that is a form of begging. Oh please Mr. VIP open this quest for us little peasants on elite. Get over yourselves.
Lastly, elite unlock is not the only perk VIPs get. It is funny how you forget how much you really get and thus do not completely understand just how much it costs premiums to keep up with VIPs. You get all classes and races excluding the favor based drow and fvs, all content with early access to new content, 500 TP a month to spend, 10 character slots, and shared banks. Go ahead cancel your sub and purchase all of that like a lot of premiums have done and then tell me how you fell about spending hundreds of dollars on a game only to have someone that puts $10 a month get more benefits than you. I guarantee you would not like it either.
