So a tamer's pet should be able to do the same amount of damage that a player can? I have multiple whammies (most of them ranged) that can hit for 200+ with Armor Ignore simply by equipping two slayers. To reach that damage, I had to max out both Anatomy and Tactics at 120, put max DI on my suit, etc. I'll even go a step further: One of those was converted from a sampire because of the Doom revamp, so I can also whirlwind during Champ Spawns when using that character.
Why should a pet be anywhere near as efficient at killing a) a large amount of mobs, or b) bosses, when there's an actual player template that does the very same thing at a much faster pace? You're acting like the sampire is some overpowered, unkillable pvm template that can solo everything with zero issues. That couldn't be further from the truth.
Pets should NOT be able to do the same things as players, and if they can (Armor Ignore and AoE abilities like Whirlwind), they shouldn't be anywhere near as effectibe with them. If you'd like a UO where pets are superior to players, I'm sure there's a free shard out there that would be just the thing you're looking for.
