as far as turning experienced players away goes, not really.
You dont see CoD 34 causing players to complain about how they have to unlock weapons that they may have used in the previous 33 games.
Its something big developers are including to increase re-playability (hmm have to find that article about the tricks mmo's use to rope in gamers)
Anyway, its something new, i kind of like it. It was fun when i played the first game on 0xp i actually had to use a different set of tactics and was really challenged by the bot.
Though the bot can sometimes be unfair (see: building units that you dont have and wiping the floor with you, im looking at you hover factory)
One thing i like is that shieldbot builders necro's can rez, which makes the "battle for salvage" more interesting.
