For Elric specific rules I will just stick with the Elric/LEGEND rules for Magic and character gen in general. Will use the RQ6 combat styles and all that goes with it.
I will keep Heroic abilities, but WILL use the RQ6 combat system (with a few tweaks).
People are already using heroic abilities which they saved up their points to spend on characters, so I'm not taking that away from them.
I'm pretty happy with Legend although am quite keen on giving the RQ6 combat a go. Quite like the combat traits etc and the expanded combat rules in general.
Won't be using the tactical rules, just use the standard RQ6 rules which work fine with a battlemat anyway (now the move/attack thing in that thread on RPG.NET has clarified things)..
Won't using any of the RQ6 magic (or Legend magic), as we know Elric has it's own magic system.
Will be using pacts, gifts etc as Elric rules. SO really all I'm doing is bolting on the RQ6 combat rules which are very similar but an expanded version of Legend.
I will be keeping the 8 movement rate for standard humans that Elric/Legend have (as opposed to the 6 movement points that RQ6 use)
I have also houseruled charging somewhat, mostly to keep the game flowing smoothly.
Thanks for the comments all, it was helpful.
