Those are very valid points. Thank you for going this step @khazrakh and making a post about this topic.
I really do hope the fray changes will look how most of us wish and won't just be adding "Rebellion Only" or similar.
I'd love to see 1 or 2 Regular Foil Bronze Frays in Tier 5 for example. In any case, a reduction of the Diamond Frays would be really welcome.
For the rest I totally agree with what @kheldar1982 mentioned and also hope we'll have T5 brawls on a regular basis soon!
