So recently read about a guy who didn't fancy that you can be in a big faction and war little ones, and that young/new players are constantly in hospital due to much larger level players constantly attacking them.
Here is what I think they should change if change at all.
Maybe change it so you can only attack within 10-20 levels of your own.
Example: I'm lvl 15. Therefor only lvls 1-35 can attack me.
What do others think?
I don't think attacks should be restricted to a level range. The ability to attack and mug/ hosp (relatively) weaker players is one of the core components of the game. It allows for in-game leadership, and allows players to enforce non-standard contracts such as loans revives, spies etc. (either directly or via bounties).
New players (newcomers) anyway can't be attacked by older players.
The issue you're raising is warring specific and is potentially addressed by offering diminishing returns from targeting weaker factions.
Also, this post should be in suggestions forum to be addressed effectively.
