yeh I think because the battles are so different in the two games, people complain
For example, EB is the sort of game where you could copy alexander the great and conquer and empire with a SINGLE army since the battles are much slower and are dependant on timing rather than actual attrition and fighting (after all, most casualties in ancient battles were incurred during the rout or so ive heard)
To me personally, RS felt like one of those games where you had to fight through a lot of stacks using a lot of your own stacks and then replenish them quicker than the enemy. (this was exactly why it felt like vanilla to me)
One more question. Since I've never played a late game RS2 campaign. Im asking, Do you find all of your late game armies consist of only professional/elite troops? Lets ignore Rome as a faction for the moment. Consider Seleucids, Ptolemies, Macedonia. Would your late game armies consist of only the best or second best phalanxes for line troops? Only your best or second best heavy infantry as flank guards?
Answering this question will tell me a lot about the game.
