It really depends on the tone. If someone gives me tips while acting all condescending, I'm likely to do the opposite just to spite them but I do look into the tip - if they were right, I'll take it to heart.

I've seen quite the opposite however. Last time someone gave me tips while leveling my astro, they were like "please don't take this poorly but I think you should use this and not that" ... it's like people are afraid to give feed back cause people flip so often. I thanked the guy, did as they said, gave comm at the end. /shrug

So yes, tips are welcomed just don't be a douche when you give them. Likewise, don't be a sensitive snowflake when someone tries to improve your gameplay.
