That said, for me, grind in GW is anything title connected.
I think the irritation I tend to feel stems from having to go through a great deal of graft, outside of my current goal. Especially when that graft seems to have no logical connection to the goal. I never had any issue with not being able to afford prestige armour, for instance. But being refused service? Give me a break.
It's not just about having to collect points, either - it works the other way too. Believe it or not, for all my title griping, I've actually been pursuing one lately. Nothing hardcore, just collecting points for Sunspear, whilst pursuing primary quests on a new Ranger. I managed to hit Castellan, on the journey to the Bone Palace. Guess what's irritating me now? No more points until hardmode! I wouldn't even know that, without wiki - I'd still be clicking on priests, only to be given some vague nonsense about where my legend will be written. What's the point in the interruption? It seems like whether I choose to pursue titles or not, they still all end up making me feel like I've hit another pointless roadblock, because a designer had a far too stringent idea on what order goals should be achieved.
It's as if Grind is the name of some hungry boa lurking in the background, looking for any sign that my journey is feeling rewarding, at which point it slithers in to crush the fun out of me...
So I guess the things that make me "feel" grind are lack of freedom, too much structure, pointless roadblocks, etc.
