You may get MK through the Meteorite event even as a F2P player, however without a relatively high LSI build it requires stacking Full Potions for a while, and then you're not even guaranteed to get him in the Legendary Chest.

I don't know your level but since you're a long time player, I assume you're not high LSI. So you're probably right about not caring about MK.

Barbarus is easier to level than Dolomar (requires less XP per level), so you might want to level up Barbarus first. If you have Aggressive Hero Potions, you should probably use them on him. But frankly it doesn't matter that much whether you level Barb or Dolo first. Just put the one with the best stats first (unless you're trying to level one up and put him in front for that reason, but you'll deal less damage).

When Barbarus and Dolomar have better stats than your Sahar, you can remove Sahar from your alliance and put Moonlight Dragon at the 3rd spot (he'll have the worst stats if we can't promote him easily, while your Barb and Dolo should both be 5 stars - even as a F2P player it shouldn't be too hard to reach, if you've saved FP for Favor Generals).
