Upgrades should always improve the ship! (Burst is a bit broken)

You don't run out of upgrade points as long as you continue grinding. Therefore anyone can have as many op weapons as their fleet can support. That's what I think we should avoid.
Lurkily said he disliked having a set formula for winning the campaign. If they make upgrade paths for the weapons, it adds challenge and variety. If they make a fully upgraded weapon the most powerful variant of the weapon, what do you think everyone will do every time? You've got another formula which is even easier to figure out than the one you use now.
