Bloodlust have 2 issues, it's too powerfull (it should only give like 50% more damage) and it cost only 50 mana to cast it. With 50 mana the paladin can only heal 8hp... think about that. The bloodlust should cost at least 150 mana and the heal should only cost 3 mana per hp and/or give a 1 hp temporary shield per 3 mana.
and even with shield or 3 mana per hp, 2 bloodlusted ogres will still win vs 2 paladins. Let's say the paladin are full mana and ogres the same, they cast bloodlust and attack. The paladins cast shield (+85hp) on each other. Let's say the basic attaque is 1 dmg per second. So the 2 bloodlustted ogres do a total of 90+85(shield)=175hp damage in 29.2s, while the 2 paladins only do 58 damage. Then the 1st paladin die, the 2nd will even die before the 1st ogre die...
