As people have said the ui is getting a full overhaul in june/july.
In regards to The getting stomped part my advise is don't rush in. Accept that your opponents are in better ships and have more experience than you. Play accordingly. Make sure you focus fire on 1 enemy as a team by using the fist flag.
If you are in a destroyer don't be afraid to engage at long range and retreat early. Also don't be afraid to rush their healer and trade yourself for him.
A Healer is the best way to learn t4 in my opinion. The single most important thing about healer is positioning positioning positioning. Make sure you can see your team, make sure you have a route planned to the next spot and make sure the enemy can't see you. Keep an eye on the radar and the pointers on screen and make sure your flag every enemy you see. Call focus fire for your teammates (generally enemy healer or whatever's weakest) but don't be afraid to change the focus fire tag to a destroyer or corvette that's coming for you.
The biggest difference is get yourself a squad and talk on comms. This is a team game and a full squad can still play And win against t4s.
Finally consider that if you come up battling And training in a t3 your Going to be a monster in a fully kitted t4
