ill answer u in 1 sentence: Because when ppl are not forced to build/join bigger sides and dont fight each other cos have no objectives to fight for, server is boring and unplayable for most of ppl.
The only thing that i rly dont like is no teleports inside TOI, it takes way too long time to regroup after lost fight and it discourage to pvp a lot (ppl either dont go toi or relog in toi when enemies come). This sh1t should have teleport atleast to 5th floor ><
