That would be 3 * 4.5 = 13.5 for the longsword. Your math is right, but you typed the wrong numbersDaedrova said:3 * 5.5 = 13.5 average damage for the longsword.
6 * 3.5 = 21 average damage for the greatsword.
7.5 damage on a daily power is the equalizer?

Also, note that 7.5 damage is over half of what the longsword does. 150% is quite a bit better than 100%, I'd say.
Your encounter power damage would be better too.
2 * 4.5 = 9 avg longsword damage.
4 * 3.5 = 14 avg greatsword damage.
That's 5 extra damage for the greatsword every encounter, which is again over half the longsword's average damage.
Remember crits too: critting on a daily with longsword is 24+Str, critting on a daily with greatsword is 36+Str. Encounter power crits are 16+Str and 24+Str, respectively.
I'd say that's worth it. Add some two-handed fighter powers that let you add more damage on that, and you're golden.
