Oddly enough, I think the current Steel system is kinda neat. The only problem I ever had was GOD-DAMNED SERVER CRASHES.
Ain't nothing like setting up to login every 12 hours (just before I headed off to work and then when I got home, and then once again before bed just to be sure) only to find a server crash fucked yer shit up. That's really the only complaint I'd make.
But I like the idea of it being difficult (people are complaining about it, so that goal must have been achieved) to make High Q Steel. Never thought it was too dificult to make any Q Steel though... And this is as a more casual player.
I even like the idea of Temp-Q, even though it does lend itself to macro-ing. I don't know what other things can effect Steel Q (apart from branch Q) but why not just add more weight towards the skills when it comes to how that Steel is used? IE: When it comes to making that Steel into a weapon or armour, Steel Q matters but it's most effected by Smithing and tool Q.
... or add
some kind of Wootz Steel (Chuck in Wrought Iron, Iron Ore, Charcoal and Glass - the Q of which would all matter - in order to up the Q or something I don't know, I'm just pulling shit from Wikipedia here).
