RTWP is not the problem. D&D 2nd Ed. was. Melee characters did lack tactical depth, with almost no other choice than hacking until the sword connects with the target (it changed a bit with high levels and ToB) And there was not Attack of opportunity either. There wasn't much positionnal gameplay (except for backstabbing may be)
I mean , take a look at Pathfinder : it is RTWP, and much more interresting that Baldur ever was (gameplay wise)
