I would say it's more proof that you survived a particularly hard raid/dungeon and needed team work to overcome it.Really? I never understood why people brag about the loot they find, it's all random number generator, if a epic piece of gear drops for you, then you're lucky, nothing else.
To the OP question, GW2 is free so try it first. I did get bored of it but not before getting a character up to level 80 (top level) and enjoying the journey.
I did the same in WoW. Got several characters to top level, did some serious raiding but got bored of that too.
In fact I would say that MMOs in general bore me now. They require too much attention to get any progression.
Prefer the drop in and play style of single player. Skyrim (with a ton of mods) for the win
