Or, what has been broken all along is still broken, but we probbably shouldn't expect much....
Plarium has actually proven themselves totally incapable of fixing any Arena Mode, and all 3 are susceptible to extreme Farming by Late/End Gamers and 2 of the 3 cause extreme frustration for Early/Mid Gamers.
I remember when they introduced G5 and tried to adress the underlying issues of Classic Arena by giving G5 a progressively competitive matching algorithm. Classic Arena became more challenging for a short while, and I thought it was awesome.....until that algorithm made it impossible for anyoen to get into Platinum, which then broke G5......Plarium's answer: get rid of the competitve macthing and send us back to farming....
I won't even bother to spend time talking about how effed up 3v3 is in this thread....
IMO, Live Arena functions better than either of the other Arena Modes, but that is from someone who has been engaged with LA from the start and is over 18K points. However, I can only imagine how frustrating it is for lower level players.
