Melee boxing heroics?

[MrHepp]

Most multiboxers play tank + 4 x caster teams (for very good reasons) but I decided to try a mixed team of 5 different classes and a couple of melee chars from the start, and now I am stuck with them.

I don't have any problem doing nice dps with my melee chars (it took a while to practice the rotations, but I've got a good hang of them now). The problem is when they have to move away from AoE attacks, like the whirlwind from the first boss in Nexus or the colossus boss in Gundrak. Then I have to get them in position again, and when I finally have got them there it is usually time to run away again. They can't deal any damage, the fight just goes on and on and it all usually ends up in a mess.

I would love to hear from the other melee boxers on this forum which heroics you have cleared and if you have any advices regarding tactics. So far I have cleared UK, CoS, DTK and Gundrak, even if the colossus boss gives me a lot of head ache every time I try him. Sometimes I skip the lich boss in DTK as well. I usually run in into UP, HoS and HoL too to kill the first bosses to get some emblems, but the third boss in UP, the event in HoS and the third boss in HoL seems impossible (I have only given them a couple of tries since I don't like wiping and paying repair bills It is so much easier to single-box them in PuGs instead.)

This is my team:
Protection paladin tank
Retribution paladin (or holy paladin)
Resto shaman (or elemental if the paladin heals)
Fire mage, feral druid, combat rogue and arms or fury warrior dps (any two of these to fill up the remaining dps spots)
