Yes. level 10 weps should not be available for sale. According to vanilla FL, lvl 10 are just prototype weapons. Weapons are from 1 to 9, with 10 being prototypes that are then named and given a valid level before going for sale.
Take for example the firekiss II, which has the same power than a weak CODE NAME. I always thought of that weapon to be the final product of one of the codenames you got from the old battlefield in Sigma 13.
The purpose of the mod is to add content to the vanilla FL and expand it. but i think we already have gone further that that. Either way, that is for Igiss to decide. If to keep the mod concept, or go a step further.
As i said if we fix the firing arcs, battleships will have to get more turrets according to side coverage. For example, an Osiris wont get many new turrets as that ship can cover itself very well with the ones it has, but a RH BS will, as his coverage sucks with less than 18-20 turrets.
And that we crank up all the weps does not means that the new players will have a harder time. The starflier will get upgraded too. And we can leave Liberty as an easier place so newbs can get used to the mod there.
