These has been an issue for more than a month now ever since the word "Meta" has been a thing. Honestly, no one knows why they're taking so long to take actions on many more issues like the removal of the shop and color kits.
However, if they're really busy during those times then why did they had the time to create and implement a more complicated UI yet there are other more serious issues that must have been taken issue off like the miscalculated wins and loses and the *CENSORED* ranking system. Furthermore, if they just took the time of instead creating a new they should've take notice of our complains like the crappy placement and effects of pads.
What I'm really frustrated about the admins is why they don't speak out loud properly and say "Hey, were working on it" but no, they just keep their mouth shut.
To answer your question, top players basically mostly spent money on tokens until they get the items they needed to and Heat Controls is already a thing earlier since, it's just really the overused mythicals like Lava Spray that give a huge use of Heat Controls now.
And yes, LEGENDARY HEAT CONTROLS NEED TO BE A THING also electron fields I mean it would be rude to leave poor Electron fields alone
