There is no "sore loser" about it, people just don't like the whole, kill players, claim land, raid chests, unclaim. Which I agree.
When people go and make these dull ass, ugly obsidian bases and underwater, they think they are clever and using their intiative when it just dulls the game for everybody.
Imagine if everybody did tht, it would be completely boring and no attacks.
It's easy to accuse people of being sore losers when your in a position where your completely safe and secure.
When a player is on from that team, you can destroy that obsidian and gain entry into the base.
You talk about it not being fun attacking an obsidian cube under the water. I can't speak for the other lads, but I had great fun trying to figure out how to stop the water source blocks above the roof so that I could break the obsidian without drowning.
The problem with a factions server is that everyone has an opinion and no matter how many changes are made to the rules, you never going to please everyone. I know that AWE and MnC were no happy with the new changes but we adapted to them and used them against Creeps.
