Again addressing Thunderwolf cavalries, they are meant for destroying units upon units of troops, but are also recognized by the player themself as a unit that will be targeted immediately, it's not our fault as spacewolf players that we take advantage of the openings you leave in your army by targeting the thunderwolf cavalry which you KNOW will be your own downfall. Tie them up in close combat with puny units like basic troops and take out our long range guys then go back to firing your heavy weapons on the thunderwolves. I mean really, it's not impossible to take them down.
I haven't played 40K in awhile, but have to say that traditionally there are two arguments best left out if you are trying to rationalize that your army is 'not cheesy'.
One is 'Hey, its not my fault, i didn't write the rules' and two is 'They are not impossible to beat.'
Both total red flags in this department.
Working both into one paragraph is basically saying 'Space Wolves are not cheesy because.... ok, what the heck, actually they are.....'
