You are wrong. Most towers dont but some do. So far towers on the three day cycle platform had gear tied to brutal difficulty for every available tower. For example the last tower group on there was Johnny/Sonya and it had 5 towers. All five towers had extra gear for beating brutal. Only group and tag battle on this platform didnt have gear for brutal as they dont seem to have that difficulty option.Brutal difficulty does not give gear or skins! All you will get is augments
Just pointing that out so you guys don´t waste time grinding that difficulty for nothing
Havent seen extra gear for brutal on any other platform so far.
Edit: towers that give gear on brutal give it the first time only. So you can easily spot those. Only problem is if you Ai fight alot you likely miss to unlock brutal difficulty.
Edit 2: just had gear tied to brutal difficulty on the 3h platform, so its not just onnthebone platform
