Waerloga the Chicken Weakling
I imagine this has been said already, but I think this dead horse needs to be beaten some more regardless. I think the Dragonlord must have been hit hard with the nerf bat at some point in the beta, because it sounds like he was actually fairly challenging based on the ancient thread I found on him from back in February.
As he is now, he's a complete push over for the sort of army typically brought against him late game. The stun effect he has on melee attackers and his fire breath attack would make him a tough end game boss if he had the normal number of perks a level 20 champion should have. In his current state he has maybe 4 or 5 total on the challenging game setting. This means he has enough survivability to maybe get in 2 attack rounds with some luck. The game I just completed he got in zero attacks, although to be fair my army was probably stronger than normal.
Assuming all victory options are enabled, the sand box game ENDS after he is defeated. He should be the toughest enemy in the game by far. Even powerful armies like the one I brought against him should experience some losses.
The other thing I don't care for is his displayed name in game is simply "Champion". That's quite lame. Why not show Wearloga or even Dragonlord? The name you guys came up with is not bad imo.
Anyways, for now I'll just attempt to go in and mod his abilities for my own future enjoyment. For those that are not going to bother doing that sort of thing, they will undoubtedly continue to be dissatisfied with the master quest end game boss.
