Which starter weapons are you referring to? The only weapon class which suffers from noticeably bad starting weapons is bolt actions (CS LR4) and PDWs, but seeing as all PDWs outside of the VAL suck, I don't think that's saying much.
Regarding the process of unlocking weapons, I don't think it's bad given the point requirements, but I realize that what I consider trivial and what the average player does are two different things.
The attachment system, and this DICE version of russian roulette with battlepack-specific unlocks (namely scopes, and flash hiders for bolt actions; the rest are just copy/paste attachments which fulfill the same statistical adjustment) is ridiculous.
Oh look, 3 25% boosts, a "long range emblem", and an IRNV for the M1014 in today's gold battlepack, followed by 3 25% boosts from the bronze battlepack. I'll try and contain my excitement.
