I like the new Inv effects, they suit my brute infinitely better than the hideous hideous sparklies.
Dull Pain clashes a little, I admit, but otherwise all is well and I'd prefer it not to be changed back.
DON'T eat muffins while I'm developing you.
Pants! Turkey Magnates! A man in a box! Rogue AI! Come one, come all, to arc ID 10107 - It's [i]'Not as long as some other arcs'[/i]!
I'm not a fan of the new GFX either, mainly because Unstoppable is completely lost inside the other effects.
How the hell can you let everyone else know you're an unstoppable walking tank of doom without the disco ball effects? 
I love them, if a team is doing great without a /Inv and one joins he lights the place. And wether he is a good player or not, he makes everything feel less evil. Plus they match my /DA set
When I heard about this from our Mary herself here I took the nearest oppertunity to look on my Inv/en brute myself and well... not impressed either. It looks to me like a bunch of cheap xmas tree lights flashing in a inky black fog. And at best just looks too much like dark armour anyway. Backed up by someone saying it matches their dm set.
Now I know how peaved our Mary here is and while I dont feel as strongly myself I do sympathise that when you get attached to your toon a change you dont like doesnt seem trivial. And in anycase I dont much care for it nyself as I have said. Not a step in the right direction in my opiniion. Taking the colour out as Krazy_Mary suggested maybe? Or something else. Some good points here on the practicality of it too worth noting.
Could we press the devs to try another effect?
I think if they decided to do the same with the colours of dark scrappers armour in CoH there would be an uprising, I mean it looks a bit evil doesn't it.....maybe a nice pink tint would make it look nicer....not a pleasant thought is it?

I don't think the colour is a problem, but having seen the new Invul effects on a friend of mine I do think they need to make them a bit more transparent.
I have been shocked a disgusted by the colour changes of some of the powers in our power set, once they were a kaleidascope of colour, now they are an inky blob of blotchy black. I mean if we had wanted an effect like this we would have rolled up Dark armour brutes. I know the DEV'S wanted to make it look more 'evil' but they could have done better than just leave the effect but take all the colour out.....come on we deserve better.
Lets show them that we aren't happy & that we want a better look for our characters
