I'm currently playing another MMORPG and like with all of them the grind process is obvious and the random drops are random however the primary difference is that it's a consistent grind and when you are grinding for better equipment the random drops don't make you wait very long before you get something beneficial or at least marginally better than what you are using. For stuff which is clearly time gated the "rules" and waiting time is clear and you know exactly what to expect and when to expect it.
I find the grind there tolerable, just as I found GW2's grind tolerable as well at first, mostly because I had better luck with character piece drops than many other players, but GW2 finally lost me when they dramatically increased the grind as I closed in on finishing that Sticker Book.
I know that grinding in these games is unavoidable and exists to keep players coming back and interested but I hope that if they produce a GW3 they have the decency to keep the grinding consistent from start to finish and don't insert the deliberate slowdowns and long drawn out and evidently random and inconsistent time gating that they did in GW2.
