Rather make them smaller, its easier to catch at a glance than transparency, though transparency works too. Good job on differentiating enemies and friendlies, and also a question - will vehicle markers be faction-oriented or they will transform into some abstract markers, related to vehicle role?
Will the reload indicator (AKA The green circle) be replaced with something else more "Warhammery" and that fits in with the rest of the HUD? I was thinking, instead of having to scroll through each Warp Power a Sorcerer has like they are weapons, we could have a sort of "wheel" which opens up and tells us all the spells we have, so we can easily switch within a moment rather than having to scroll through and guessing what spell we have currently.
I think Brent answered this to me once, he said that at launch only one space would be allowed if I remember correctly.
Are Guild Tags built in-game planned for post launch or pre launch? Just so we don't have to waste space in our character names, it can just appear on our person in-game.
When guilds come in (I can't say when just yet), we will have guild tags in the player nameplate, and they will not use up character space.
