Survival+
a good substitute substitute for OpSurvival, upon its reset, would be Survival+. but what would differenciate this gamemode from all the others ExtremeCraft already has? vanilla. sure, features such as Auction House, TP etc. would still be good, but what other gamemodes don't have, is raw gameplay. all you do in the other gamemodes is spam and pray your enemy's armor breaks faster. i believe some things that could make this gamemode interesting are, for example, allowing certain things to be used in combat, which includes but is not limited to: XP Bottles, Ender Pearls, Elytra, Cobwebs, Riptide Trident. alot of people nowadays only like farming, because the PVP is found to be boring. even in LifeSteal, a gamemode where the main objective is PVPing, and you can't even PVP properly? we've seen the drop of playercount LifeSteal has had. 150 on release and hardly 30 on regular times. other things that could go along with the gamemode might be McMMO, which also makes the gamemode more interesting and the PVP overall, and last but not least: Custom Enchants. having some of the Custom Enchants that there were in OpSurvival would be good, but maybe not all of them, as some were definitely TOO overpowered, and gave an insanely unfair advantage.
Other things that would make the gamemode different from the usual:
https://www.spigotmc.org/resources/raidsperregion.87585/ - Plugin for PvE server events, encourages players to explore the world and therefore risking of dying because of other players (would also love to see Outposts get added)
make items such as Enchanted Golden Apples, Elytras, Maces relatively harder to get (not as hard as Vanilla but not as easy to have double chests filled with EGaps)
https://dev.bukkit.org/projects/infernal-mobs - another plugin for PvE improvements, where mobs have a chance of becoming "infernal" which makes them sort of mini bosses
also if possible, increasing the mob cap and making Spawners harder to obtain. i personally have over 300 Spawners currently. seems a number really unnecessary, doesn't it?
i know some of those might make the gamemode a little too different from others, but if all gamemodes are the same, where is the fun in playing one instead of the other? that's what made OpSurvival at least a bit different from the others.
