As you noted before we started, Sentinels are the only antiarmor the Guard has before Tier 4, and Sentinels are weak against other vehicles. You should have directed the Dreads to go after my Sentinel instead of sending it careening into the nearest formation of Guardsmen. Of course, I'd have had the Guard force melee with it to tie it up within lascannon range, but you don't need to do my job for me.
Also, you were going for an early Take and Hold win. I know that you can't build gun turrets and such around Critical Locations unless you're Eldar (webway gates are cheap like that), but you, like so many other people, overlooked mines. In fact, mines are great on that level in general; had you rushed me, you would have found your Marines blowing up everywhere they stepped between the front gate and the end of the path to my base proper.
Also: Because I can't resist bragging, I do love that coup de grace I applied. Ph34r the 700+ damage of the Earthshaker round.
