@Iron_Guard8 you mention that GW is already 7 years old, and of course GW2 is 5, but what does worry me is that GW2 is already showing its age and more so than GW; probably because GW2 has always been plagued with bugs of one sort or an other even while it was being supported, and not so GW.
When playing GW2 I experience problems such as:
1) Stock Pea disappears from my character list when playing the Town Hall quests
2) The game freezes, particularly when I use the Engineer's Jackhammer
3) The Kill Counter does not register kills properly (that is the most debilitating error of all. I have let off a Shuck Shot right in the face of a Toxic Brainz in Legendary mode. Knocked him out, but no kill is registered! And knocking out a Tox B in legendary mode is undoubtedly the most satifying of kills.)
4) I get thrown off the server in mid-game (Can't quite remember if this happened while the game was being supported)
5) When entering a game I have found myself placed underneath the road surface and can follow players walking above me.
Bit of a pain, as I really like GW2 and prefer it to all other games in the Garden Warfare franchise, and would hate to see it become unplayable for the reason that @stukapooka puts perfectly, namely overall polish.
