I think what you asking for going to make the game mode worst , because if you going to party and Iam going to soloq Iam going to end up with bots teammates while your team coordinated .
Like I got recently matched with a glaive , went stormcrown spellsword clockwork Tornado trigger , there is a recommended build why you doing this , and the enemy was playing good and following the recommended build , so I can’t tell if this guy trying builds on casual or he just hated that glaive always needing energy.
The same for skaarf in your match he wanted a basic attack damage from aftershock and sorrow blade , double fountain from joule , the enemy was trying to win , they probably thought the answer to bounce damage from you is the double fountain hehehe , I don’t know I think casual is better without party .
