As a person who's got a lot of time into this game, I wouldn't. With the expansion, they managed to turn a good game into a shitty grind fest. It's just not fun. There's not as much to do at max level as there was previous to the expansion, which is stupid.
It's like they took everything good they did with rift original, and threw it away and went with grinds foreverything. Reputation grinds, double rep grinds in some cases, and other grinds. They nerfed gear badges and pvp gain significantly via different methods to make those grinds even worse too.
There was even a way to do old dungeons at lvl 60, where you could get maybe 1 PA point every 3-4 runs via old dungeon badges. They decided this was way too OP and nerfed the shit out of old dungeon badges, now the old dungeons are ghost towns, just a stupid decision all around. Repeat this kind of decision making all over the place.
They added a new feature like a invasion/defense thing forgot what it's called, they had mobs spawning at an insane rate out of these invasion/defend events at release which was awesome and a lot of fun. They significantly decreased the spawn rate to horribly boring because some people, god forbid, were using it to level up.
Even their content updates have been mediocre and infrequent since the expansion release, definitely not worth $15 a month. If you've been subscribed since November and paid for the expansion, that's $130 you've spent for the expansion plus a couple shitty patches.
They had some great ideas that made it a unique game that was better than WoW in many aspects, but they threw all those unique good things away and decided rep grinds and harder treadmills were the best thing to implement.This kind of decision making fits with their company strategy though, leveraging their rift original success on 3 new unproven mmos and failing horribly.
