Rather than start a new thread, this seems like a good one to bump. It's still good reading even now.
So, we have 3 new heroes. Everyone has had a chance to take them on a test run. What are the decisions? I'll begin.
1) Horse Lord. I've used this guy the least. His group move ability can justify grouping him with your starter/main hero and walking him around until he becomes useful. Somewhat handicaps the main hero's xp gain ofc. I haven't leveled him up in a game where I really got to use him yet. Rather sad that I haven't gotten to smash anything worth smashing with him. People leave the game by the time he's leveled. Igor has been reported to group him with a Valkeria, and that sounds just wonderful. Of course he can be countered and so can that strategy: Grand Archon.
2) Barbarian. The new favorite? He's an expansionist. So, you know he's my favorite. I take 25% of "Battlefield" in 10 turns; you had better believe expansion is just what I do. That was before this gem. He is the one to use if you want to preserve your units while capturing neutral after neutral. It's possible to gain all of Airstream in a few rounds with him. Not good in hero vs hero combat, but still a useful raider or bodyguard in mid-late game if he's already leveled. Nearly the god of small maps, but a level 1 Assassin can embarrass him for 400 gold, so don't put all your eggs in one basket.
3) The Assassin. I see a lot of this guy from other players. He needs leveling and either hero support or items. People are using him right and left, but I generally just roll over him because he's not leveled. I think the 10 UL is drawing them in without proper consideration for his strengths and weaknesses. Looking forward to seeing what he does on defense in one game; got him to level 5 so far there. Support hero, right? Unless you stack some crit hitters with him and slaughter stacks in open field.
