Twist in smite. Use your other 6 feats to get 12 more MP be at 107MP all the time regardless of your target.
Optimize your attack rotation? I think you mean only pick quests with undead and evil outsiders nothing to do with attack rotation. Maybe you don't understand but 85 of that melee power is only available against undead/evil outsiders.
You are adding in the base but only the melee power gets multiplied so its (300MP * 2 + 100) /100.
Misleading analysis..... Pot kettle. You've argued that fighters using just kensei are weaker than barbarians using FB with twists and filigree. Now you're doing the same with paladins, and your math is screwy in ways that benefit the fighter - i.e. Storms Eye is on average 6 points of damage due to a 50% up-time and being at 25 or 1 depending on how long it's been up. You figured out the equivalent for one cut without issue. Also, greataxe is 20/x3 base so it's 19-20/x6 with improved crit on a FB. FB doesn't get a crit range increase so you don't get another +5 to your crit range multiplier. The comparison is 28.75x vs 29x cause you shouldn't double dip and add extra damage from deadly weapons to both your base damage and then as a modifier on your critical profile if you're doing a line by line comparison.
I heard the first R10 Legendary shroud took two and a half hours and there's 4 shrines. I'm sure the extra 2-3min of haste boost per shrine comes in handy.
It's good that paladins are the best in some situations, barbarians in others, and fighters are strong in all situations just not the strongest in all.
Also, Henshin Mystics are the ones that need some enhancement changes fighters are still strong.
....plus fighters kensie get +10 to all stats so they could hit 86 intelligence and get 3 more damage out of KTA than a paladin can get out of divine might.
