Yes, I know Might is additive. What I meant is that when every bonus is additive, an extra +300% from Might will reduce the need to invest heavily in synergies. Leap Attack, for example, already grants a +670% damage bonus at Slvl 20. Add some strength bonus and a Might merc and you'll easily hit the +1200% mark. At this point, maxing out Leap for its syngetic bonus will only improve your total damage by 15%. So is a 15% increase in your damage output worth 20 skill points? In this particular case, it may be since Leap has some useful side benefits as well, but the same can't always be said for other synergies.
Edit: Vengeance and Conviction can be seen as a special case here, since the Vengeance skill only multiplies the base damage from weapons to produce its elemental damage. This does not diminish the effect of a Might merc however. As aura stacking is no longer possible in v1.10, a Paladin who wishes to use the Vengeance and Conviction combo as his primary attack will not be able to flash Fanatism and/or Meditation on the side. If this Paladin also chooses to invest skill points in Resist Fire/Lightning/Cold for their synergetic bonuses, he may find himself hurting badly from a lack of life and mana leech. A Might merc can help tremendously here by increasing the physical damage of Vengeance and increasing the amount of life and mana that can be leeched back from your attacks.
