Runes after level 50.

I`ll just give my 2 cents :
1) as previous rely said it, in Ap/Cw was same because in this game you dont have to max lvl all skills, but make decisions in RPG sense what to pick for upgrading and go in that direction
2) bugged ship, no solution other then hoping to get fix in next patch
3) as said above trapper medals is best for Mage due to his high intellect and with it high dmg for trap spell (i had max dmg around 20000dmg + poison effect with 84 intellect if remember correctly). Max lvl medal, lots of traps and with it you have free obstacles to keep enemy army from reaching your low leadership troops. For Warrior/Paladin not so much because they have bigger army and defeat enemy with it, not spells, but free trap is always useful.
4) you`ll lvl it later in game.

i maxed trap medal with skald quite easy (on imposible). It's so easy to bait them with summons or low level units (draids -> thorns in my case). And you have a lot of tools to get enemy at low health: same sumons (thorns can make 1/2 stack of their size, and so on), different level rage skills, so you adjust their total life with it, and then bait. It gets easier after 2lv medal, because of +% trap damage.
