Mythic raiding today is nothing like the old heroics. There are tons of abilities that require keen focus on a single character. This has made them near impossible for us and has turned a lot of people off to them in general.

It's impressive you managed to kill one. The rest, like the spider boss? No way. Maybe Il'gynoth. Maybe Ursoc though that is very hard with one tank.

Just throwing my 2c in after doing these for balance of power rewards solo.
