UW doubt

Greetings.

I got my 3 first UW soon after joining the Game: BH CF SM

Now i just unlocked the 4th... ILM

I should start thinking in respec? I should just keep going?

The biggest losses if i lose My actual progress would be: DR epic card. 11 card slot unlocked. 4 labs unlocked + 2183 gems (trying to unlock the 5 labs). 1 epic module. 5 relics (5% crit factor, 5% abs defense, 2% coins, 1% free attacks and 2% lab speed).
