If your FGU breaks, as you say, regularly..it might the ruleset you use perhaos mods or exts. I would tell it like it is if my fgu experience was as you say but full honesty fgu has been as solid for my games as fgc was and this is for the last few months now.
I've no worries that fgc support is ending, if that means more time devoted to fgu support, features and products all the better.
Edit...going back and reading other feedback ..yes my fgu takes a little to load initially but i have a ton of tokens anout 3 extensions and 2 3rd party mods.it clocks in at 2 "real" minutes . When its loaded though my session is good.
The preload time doesn't impact if ince its loaded it works fine. If it was slow DURING the session then I'd complain. But i load fgu 30 mins before the session starts and i go have dinner or something therefore it doesn't frustrate me since i dont sit and watch it load 90% of the time.
