The practical approach might have been all MC mechs come with 1 mech bay and C-bill bonus while c-bill mechs are the plain ones.
- If they just slap on 30% to all mechs people in the forums will call it a lazy PGI cashgrab.
- If they make unique camo/geometry for all converted 'heroes' then it takes more manpower from other things and sales are not guaranteed to earn enough returns for the effort.
- A method to upgrade a non-hero mech to have 30% is none-existent sytemwise and has to be build from the ground up which requires changing how the DB is structured.
As mentioned above, a permanent install module with a c-bill bonus would be nice and easy. Make it 15% or something if the 30% is too good a lure to get people to buy heroes and packs.
