Syndra buffs are not exciting
All we had to wait for were passive buffs, but then we got a mana per level buff. It's a good buff, with this Syndra will have the third highest mana per level champion and the second highest mana when it's 18 level. But it's not interested. You can increase as possible as of a champion's stats and make him/her overpowered but it's not exciting. It's just going easy.
If there are still passive buffs then just remove the mana per level buff. It can cause to an overbuff.
