wel think about it. yeah they can get better within their own skill as a player, but their character can also get better skillwise as well. im sure it wouldnt be very drastic at all anyway. at most 20 % improvements all around. upgrades and experience systems add depth to a game, something seriously lacking from current playerworlds.
it seems your thinking about this like a soldier vs. a terminator.

the line of sight system can probably be best explained as a first person shooter without the first person view. and a picture.
