Don't know what to say to all this talk about invasion tiles...they're the easy ones I use to level my low 5*s, who never even have to step onto the battlefield. I take the enemy tanks head-on with my highest 5*s and my two remaining 4*s, and it pisses me off when I lose even a single tank to a mis-timed defender shot. Commander's level is 46, Sarah's level is 35. Are you guys not Medium deathballing or something?

I do have to replace the lowest four 5*s with high level 4*s for high level PoC and Ocica map runs because they tend to use all of my available tanks, but other than that I'm not seeing any problem with normal gameplay difficulty, and certainly not invasions. I did have problems with the scaling on the Halloween event, though.

Also, since commander and tank levels are capped at 50 this is at most a temporary problem for EVERYONE, which is why I've been relentlessly grinding invasions for XP in the time between events. Once we hit 50 on the commander level it will only ever get easier from then on out as our tanks start to catch up.

(Should probably be noted I haven't spent a cent on the game...FTP FTW.)
