One thing that bugs me is that it's the Advent Loyalists that got a beam weapon damage increase via Titan research when really, it's the rebels' Eradica that has half a million different beam emitters. Logically, since the titan requires so many beam weapons, it would make sense that researching the titan would lead to advances in beam technology.
I could be wrong.... but I think that although the Coronata has fewer beams than the Eradcia, it actually has more beam firepower. so a 5 % inrease is helpfull... especially if you consider all the other damage buff of the AL.
Of course, still nothing beat Vasari Phase Missiles..... makes all weapon upgrades and buffs + Energy Aura look like a pathetic excuse in comparsion.
