This Is a HUGE Design Flaw
Being punished for being with your team. Advantages of Being With Team: If you are fed: 70% chance of winning a teamfight Take turrets faster Total: 2 Advantages
Advantages of Being Solo: More XP Take turrets with less risk ALWAYS a higher level than your lane opponent that left to help his team Can push through inhib without disturbance while your team distracts More gold Total: 5 or more advantages (can't think of many more but i know there are)
I thought this was a "teamwork" oriented game. But it isn't when you are PUNISHED for being with your team.
