I appreciate everyone taking the time to respond, n I think a lot of valid points were made through multiple posts..

I encourage ALL types of communication in ANY competitive team based game n personally I think SE should allow BOTH Text and Voice for Competitive PvP

Comparing ACT and VOIP wasn't my initial idea for this post.. Clearly ACT is a 3rd party program that is 100% against TOS so comparing the two is silly.. I think what I was more trying to say is that between the two there's one thing in common.. The player is looking for a competitive advantage over his opponents n is looking to improve his chances at gaining that Precious +25 MMR..

I think what it comes down to are a few simple questions..

1. Do the players using VOIP in Solo Queue while their opponents aren't gain a competitive advantage?

2. If so how significant of an advantage?

3. Should it be looked down upon regardless of if it's not technically "cheating" or against TOS
