Oh man, you've clearly not looked at any other game if you think there's an inherent problem with Infinity balance. Infinity is one of the best balanced skirmish games out there, the differences between "top tier" and "bottom tier" are minimal, even without comparing to things like 40k and Warmachine. I am pretty sure Infinity is better balanced than things like Frostgrave in which everyone essentially plays the same faction (with just a different hero unit). The entire time Bolts' problem wasn't that they were inherently bad, it was that other options in the sectorial were better. Now they have a better niche, which makes NCA lists less predictable. I am sure a lot of people will just dismiss those Bolt changes and play as they did so far (since nothing on that front got really changed aside from an odd Wildcard or two) while some will jump at the opportunity to try out the shiny new Haris.
