Play on a server without shops or kits. Factions once had nice builds but nowadays since obsidian and TNT is distributed for free or for little work by shops, raiding has become way too easy. Factions today sucks with all the kits and hackers. Too many owners and players have bad taste. Even then you won't get as good factions experience as there was in the past, because players have in large part lost their sensitivity and creativity. At this point it's not really Minecraft Factions, Factions servers are like a completely different game, like a poorer version of Clash of Clans with purple obsidian boxes coated in water everywhere.
Honestly if you can't find a good server then just play single player or play with your friends, or stop playing minecraft for a while and do something else with your time.
We've always had TNT turned off on our maps & no donor kits... because bleh. idk, I guess word of mouth doesn't go as far as flashy advertisements and BUY YOUR VICTORY NOW. ¯\_(ツ)_/¯
