If you say so. I find that standing idly in the open gets me killed just as quickly as it did back in ME2, and unless I aim real good and land a headshot, the Claymore isn't a reliable one-shot-one-kill tool anymore -which is why, coupled with them doing away with the reload trick, I no longer use that- so I don't think the player has been significantly buffed other than by tweaking cooldown mechanics.
The real balance changes have been applied to the MP portion of the game only, as far as I know.
Balance? Bwah it's worse that ME2 there ( talking about Gold, you can solo Bronze and should have an easy time on Silver with pretty much every char ). Shots from nowhere, paper cover, powers and mods not working properly and gazillion health on the enemies, not to mention that from all the weapons most are completely useless.
