Let me clarify. The fact that both groups run similar meta stuff, only shows that, if one can kill the other and the other can't, it's about skill level and execution. In the end, it's not related to whether skill they choose, because they all run the same things. Also as you said, MI ''CAN'' instanly rez people. And its well balanced around that. If you take longer than the invulnerable frame to MI the downed body, it will start to get cleaved/get Poison, so your MI will be uneffective. You also to have be constantly aware to MI and recognize you can't MI sometimes. You can easily distinguish a good from a meh Firebrand in WvW by his MI usage, because they all press SYG regardless. We aren't in HoT anymore, people don't run Hammer to knockback people from hand rez or signet radius. Only build that has a skill which does that is herald with glint elite. The downed cleave is very high, uncoordinated hand rez is very risky and any cast revival skill that takes longer than IoL is unoptimal. Don't expect people to preemptively pre-cast signet, or interrupt the signet (maybe in smallscale or GvG) like they do in PvP, there's way more things to worry about. Let me tell you, if they nerf the hell out of MI, people are just going to stack more FBs, because no one is slotting these new revival skills (maybe Feedback, but mesmer is dead so) Function Gyro is used for on demand superspeed and field blast now, it is what it is.
