I think the reason why we are doing so poorly in relation to solo botters is that we are forced to move slowly throughout a rift to keep the team together.
You have to set the monk as lead if you want any hope of ever being in inner sanc, Then every time the monk moves a bit in a fight the wizard moves and isn't attacking or doing anything until it re-positions itself and with epiphany on the monk he can be moving all over the place. If you enable phelons playground, the wiz basically acts as a solo player and jumps all over the map creating density, in doing so it leaves inner sanc and other various party buffs. It tries to aggro for the party instead of letting the support skills do their job.
If you don't set the monk as the lead, then you have the wizard leading the group and hes not keeping up any buffs, just moves until he finds the appropriate amount of density to start the combat routine. Often procing before a fight even happens.
I did some changes on my own, removed the barb and ran a dh for lower grs. Wiz still never died with monk as lead, have more dmg buffs, but the xp / hour is still garbage. A solo bot can just spam teleport - find density - nuke it - move on. If the 4 man wizard were to do that it would leave the group in the dust, then it would have to fight mobs with 4x the hp and dmg all by itself.
If I raise the gr, im still not dying, even without the barb, but my dmg isn't really there because the bot has a terrible time at overlapping archon stacks. I edited the wizard file that had the part about (If chantodo > 19) or whatever it was. and I set it to 1 in hopes it wouldn't sit there getting 20 chantodo stacks everytime it went to fight. That worked, but still if the bot is in movement mode it won't cast archon even if you set the archon limit to 1 mob and cast off cooldown.
If you switch to tals vyrs, the bot pops archon off cooldown, but it won't manage tals stacks which is everything basically.
In the end, it comes down to the "scripts" being too difficult for your average gamer to make on their own, and the people who understand how to manipulate the bot don't actually understand the builds and how they play. Inevitably leading to failure.
