I agree on said thing.
1.) The "stam gain in lower levels" do not solve all problems but make relics more useful. A lot of guilds have unwanted relics which they can not delete (Only that strange way to ask another guild)
2.) Limit the powerful stamina relic for each guild, maybe just 1 gain and 1 max stam (gain + max gain)
3.) I like the Reroll idea with GvG Points (Make gvg great again yeah, but with that all other suggestions are useless)
4.) COOLDOWN: If you loose a relic you have a cooldown on it like on titans. Look for new ones!
4.1) ATTACK COOLDOWN: Sorry, but if you can not get a relic after 10 times attacking, take a cooldown. Guild log was full of spam with a guild who failed taking our relic for a lot of times. With 5x group attacks (more with upgrade) it is pretty annoying.
5.) Ban that "strong" buffs for relic. How do you hold a relic when player uses Dark Curse 86%?
Reign of Terror make them even stronger. In PvP already soooo annoying - Make normal setups useful and not feeling you like you can do nothing. It would not matter if you sit in Epics there, naked or in pvp setup when you always lose because overpowered buffs kill you.
6.) Make better enchancements. Master Inventor, Thievery, Master Thief... And maybe "new" ones. I know at least one set (not hoof!) that gives you Hypnotize and hooftest has soulless enchancement too. Or Temporal shift. All strong so maybe +1
