1. If you want some m/s, try replacing your shield with a thoth buckler level 45. You'll have a loss of 12 armor but if you do thoth plate it's a loss of 15 armor and if you do helmet it's a loss of 20.

2. Warriors actually due have a significant amount more of health and armor then birds. Warrior attributes increase health, and they start out with 50 more health in the first place. Their gear also has more armor than dex gear. Warrior's also have a great buff spell (iron blood) that increases armor by 50. Warriors are designed for taking damage and protecting archers and mages, who are doing the most dps and best spells in the back.
