I am infuriated and in tears, about to quit again

As I said, I am 100% fine with that and expect that.

But the fact a no-contributor rolled and got it is disgusting to everyone who fought.

Did you call him out on his lack of healing? Did you try to kick him? If you didn't take any preventive measures, then you only have yourself to blame in this case.

Either way, just use tomestones to gear up. The beggining on 3.0 will probably be tailored toward i90 or i100 since the minimum needed to beat 2.55 is i90. Once you get into HW, you can just gear up during that.
