one thing i would say is don’t split at the start, if you go 15 left and 15 right, then we can take 30 to one side and wipe them 30v15, then take 30 to the other side and wipe them 30v15 and backcap anything capped.
not to go all illidan on you, but preperation is key, we spent the week setting a roster, backup roster and doing multiple war game tests to see what does and doesn’t work, we also had a combat formula for our roster with multiple backup plans in case anything went sideways, as well as people assigned to different roles such as defense, base sitting, etc. another thing is we have multiple reduntent people for roles.
otherwise i would say make sure you are geared and are doing arena and also working on epic specific builds, but you do need to also work on damage output. everyone on our team can top the meters when in their own game, this means that some of us can drop our max damage builds and go with tactical/utility builds to act as force multipliers.
