My opinions about usual topics... ;o)
1.) I understand bashing teams (chaos, dwarwes, orcs, khemri, etc) fouling. If they don't foul against ag-teams, it's really hard for them to win games.
2.) I don't approve fouling at last turn, blitzing players out of game at the end of turn, or fouling players when you are 4 goals behind and have no change what so ever to win or even equalize.
3.)If you don't like bashing teams fouling you, don't play against them.

4.) I understand stalling for the same reasons. If it takes three rounds for your dwarwes to score, you should score when it suits you best.
5) I can allways understand stalling for 1-3 turns to secure victory. I don't approve it if you lead by 2 goals and there is really no way to equalize.
6.) If you don't like stalling, don't play against dwarwes ;o)
7.) Hmm... if scoring requires go for it and you choose not to go for it, but to score on the next round instead, it's not stalling, it's playing wisely.

All said and done, I personally don't foul (only exception being my chaos team) and I stall only for 1-3 rounds. I stall only to secure victory or draw and only if I have no change of scoring again in the game.
After all stalling is boring and brings little spp...

By the way, if you have dirty players in your roster, don't waste your time challenging my woodies or skaven.
