they should make soloque heal/caster/melee teams only.
Obviously there will be some stronger mhc than others but the difference is smaller than in a ffa environment when it could be possible to match dk+warr+sham vs affli+Hunter+mw as an example.
But soloque as mhc could make room for a lot of new comp/speccs to shine which are not possible on higher ladder.
On AT it was aswell amazing like this. saddlybecause of not a big population they had to change it some time ago to an ffa system where you already know before the gates open when you get matched as tsg/lsp vs something like hunter/mage/hpal that you will win.
but when it was mhc the outcome of the match almsot always was decided by the individual players skills and how they played together
Good points, and as previously mentioned the problem of adjusting comps/teams can be solved through statistical data.
