As a 35T league manager, my opinion:
1. FK specialist
2. No
3. I believe that it's a cosmetic thing
4. Don't know about those hall of fame top scorer stats.
My Q59 striker (my lvl 7 team's Average Q is 51.6) scores 26 goals and 25 assists while my team's goals are 74.
His def att phy : 59 59.6 58.4
