I've been trying Sacrifice over the past few days, which is a third-person RTS with the main gimmick being you can choose one of five scenarios each time. I like it so far, but...
From the two second-tier level I've played, the difficulty varies quite a bit on the same tier. The first let me just steamroll the opposing mage over and over, while the other starts them with considerable defenses and gives them an easy shot at your base, especially if you don't know about the teleport.
There is little clarity as to what is going in combat. Enemy troops (and some of yours) will have arrows in differing colours, but mostly no health bars unless you hover over someone. Everyone starts running into and through each other, with no indication of what side is winning. At one point I though the enemy were dead and it turned out they had a dozen or so left.
One creature description has already been unhelpful. "can keep our enemies off-balance" means they get flung in the air.
