looks at the poor dead horse Time for a beating!
I think we all agree joining a game in progress that's losing soundly is unfair. Most modern games wont count it as a loss and you will not incur a penalty. Typically you're rewarded for the crummy experience/staying. I fully expect them to implement this system eventually. It'll just take time. It's a reasonable way to deal with these unfortunate scenarios.
looks at the dead horse again Not done yet.
T2s have no business in T4 battles. A player new or old shouldn't be expected to put a lower tier ship in their fleet to stop a potential stomp from happening. Especially since it's not told to the player at any time in-game. Depending on the skill of the players involved... a T4 can soundly stomp a T3. You can imagine how badly that compounds to T2s.
Torturing and griefing the player base isn't a great idea. Plus a T2 can ruin the other T3/T4's game in the process. It's not their fault they got put in the match... but it'll certainly be a liability. Depending on how many are present it's often the deciding factor. It may seem small but some people only have to have this happen once or twice and they'll write the game off. Nobody likes that amount of tilted odds. Ok maybe Dark Souls people but they are masochists.
