I am 1401 attack now and in SAM. I use Sentinels with no roguesI'm only at 420/350 and can easily get past 100 attrition with ease. If I use both a tavern and potion boost, I can get to 150 or better. Might I ask what age your in and what troops your using? At 1000+ you should be able to do 200+ attrition with ease.
