I'm not the Oak expert, but let me tell u a few things about this game:
u took Bold of the Fallen and when u came back to shop first time u bought Banded Armor and ScalMail. I think thats a little bit too much. ScaledHelm would have been the better choice, besause u cann cast your abilites (pentience I and shield I) one time more and your Mana will regen faster.
u took Divine Justice at lvl 3 - I wont, better take SoulPower for more damage
your play at mid game was ok, your team were 9 kills in front
first time you attacked the towers at the enemy portals was at the 25 minute mark, at this time your team was 3lvls above the other team!!!!! ok attack failed, because your teammates were on holidays and didnt helped u
at the 28 minute mark enemys took your right portal first time and hold it till end - at this time your team was to uncoordinated
you were the only one, who realy tried to get the flag back, your Reg tried to get more kills, and TB defended left portal
if u lose control over one of your portals at this time (catas are on the field) 1. lock your other portal, then your hole team can concentrate to get the portal back
your team had 120.000 gold, other team 87.000 gold, u wasted money in mid game for things like Narmoth's Ring, Bishops, ... ( Narmoth's Ring is a good item, but a waste when u are 3 lvls in front)
It is realy unbelieveable that your team lost this game. Good luck next time! and please buy a speed item!!!!!!!! Speed is still the most powerful weapon in this game!
