I think custom class has been left there for years and we haven't even started XD; not much I'll be afraid of for that one. Actually not sure why that one is still lingering around personally ^_^;
Revamped fishing/mining, you already saw the beta testing of what mining will be, so really not much ot be afraid of again.
WoE2, I think we all agree so far that implementing woe2 without any changes, you get problems due to low population, and that half of our server honestly won't even get pass Sword Guardian, let alone a very buffed one with a full guild supporting the Guardian(s). (and on top of that, barricades aren't working from eA anyway unless you tweak them /swt ) Similar to Infinity Tower, we adjusted it from original to suit our server better.
As for the no/less/more custom debate... it's more a personal choice thing. I am afraid that no matter which path we choose, someone out there will be unhappy due to too many/little customs.
And I think that it's fine for your suggestion. Sometimes we accept them, and sometimes we don't. Sometimes a suggestion is already in the making cause GM has similar ideas beforehand. Sometimes, a suggestion is a good wake up call, and sometimes suggestions just can't be implemented for various reasons. I didn't respond to the gambling one cause that's not really my place to decide if we add/reject/adjust it or not
