The 5v5 inhouse is nice. It was cool to play different people top. I may have to give Jayce a try after that seeing all the dmg he does. Hadn't seen him top before, but he can really abuse the meta once you coordinate your transformations. That melee bonus defense is a little much in my opinion. It was tough to harass him effectively, especially with that huge knockback.
As for balancing teams, I totally agree this needs to be a priority. I wouldn't want to play with us if I ended up with the odds stacked against me. Doesn't matter as much with ARAM, but Summoner's Rift definitely.
Just another note, I get frustrated at times too, but it's completely unacceptable to grief people on your team in our inhouse games. Constructive advice is fine, but say your piece and move on. If you go beyond that, it's harassment and I don't want to play with you. The more I play this game, the more I realize that attitude is everything. So if you aren't going to be a positive member of the team, then don't play on the team at all. Take a break, come back and start over.
^This isn't directed at anyone in particular, but I really look forward to our game nights and I think this is something we should take seriously. Everyone should be entitled to have fun with us.
