Its sort of a staple of the mechwarrior universe. Its a big part of the board game rules. Lets examine the Pros and cons.
Pro
Follows the books better
allows more choice
allows sale of items
allows upgrades
Cons
leads to min/max mech designs
less reasons to buy a new chassis
hard to judge threat until its too late.
We've been running a campaign of battletech where we have pretty much unlimited refit capability and I'm honestly not that happy with it. Too much choice. Too little reason to move on and try something different. Why pick up a new mech for scout missions when you can just refit the one you have? I'd much rather see people with a large stable of book mechs than just a couple custom ones.
I'm leaning towards limited refit ala mw4. Unless you're an omni mech you can only change out weapons for other weapons (or combo of weapons) that use the same or less in crits, tons, *and* are the same type. For example, I could swap a PPC for several medium laser, but not an ac/2. If you've played mw4 you know what I'm talking about.
