Thank you guys so much for these exploits. Without these, I was sure to not have either finished very high in PvP or caught up to numerous players who have played since the beginning of the game xD

Yes, same happening to me as well.

Brandons Trainer V9.0 by itself works but Charles causes CVE.  Well that sucked just makes it harder to win.  The AOE buff, and attack works.  My other trainer, in which the other team attacked its self no longer works it causes CVE.  I used that one half way thru PVP last season and then after finding out about using charles, I stopped using it and just killed the other team in 1 hit all the time. 

Charles does still work on daily mission, and I use it for fast farming in 12.5 and 12.2  Mags Kills the enemy in 1 hit each time, and so does Cap.  I removed the cool down on Mags Graviton Well so it works every round.  The way to make sure Mags and Cap go first is to change their initiative from 0 to 100, plus to make sure they kill everyone change attack rating from what it is to 300 they do over 200k damage, if you want more just increase.  I dont have Mags, and have not isoed cap since I wont be using him other than in 12.2.  Now to remove cool down on mags the line on mine is 173171 so it will be about same on your client.xml, change cooldown to 0.

Now if you plan on iso farming, change attack rating to 1 so they do minal damage, plus change their energy usuage on their area attack, so for mags 3 lines below where you changed cooldown is energy, make it 0 and you can attack without using stamina.  The reason to use their area attack is if you change a regualr attack into area it will hit all enemies, but you will only get 1 item to drop.  So hitting all 3 with actual area area gives you 3 items dropped.  Now Caps shield throw energy is on line 201518.  If you dont have Cap use another hero that has a area attack, preferably lvl 6 attack, plus equip an area weapon on agent in 3rd slot, so that way if you want to run a bot, you use the 3rd slot for attacks.   Now the weapon I have found in items1 is P.E.W. Dragon, just change energy to 0 also so you can use as many times as need. Also make sure for emeny to use rest for all action types that way the enemy will just sit there and do nothing on their turn.

same for me :(
 

dust off your corned beef scroll and trusty brandons aoe

same here, CVE pops up when using KHUT, maybe it's temorary like  last PVP? 

guys one question, i really hope that someone can help me with drops, how can i farm isos?

Charles doesn't work anymore, also with last XML, it's true strange
