LORE QESTIONS

1. A small question about sona's ethawl, is it a independent being protecting sona as ori's ball does? Also since Sona is ionain how does she feel about noxus? She seems like a neutral party all things considered. I don't really get her reason to join league. (side question: how would a interaction between sona and lee go?
2. How is the next story arc coming along? Im very excited for the next big installment of lore. I hoping with yoricks rework he'll be in the next shadow isle story.
3. Will there be an Frejord update soon(ish)??? I'd like to see more elaboration on the personality of lissandra ashe and sej!!!
4. Hopefully we some more nami lore.

Balancing question

1. So i have another sona question. Every season you some work on sona it usually is a change makes her good from a spot where she struggles to relevant to other support who do the same thing but better but then after the Changes you nerf back to square one. Also is power chord supposed to cancel if sona dies before it hits the target?
2. Ive sorta noticed riot likes diversity! But you also lock champions into their roles so its difficult to try new things in league that almost work to actually be half viable.
3. So i guess solo queue wont be a thing? I dont why league HAS to be a team game. My opporunity so test my self against other inviduals not paired people help to develop my own skills. Otherwise i would do LoL tournies with was the best way for me to come into contact with higher elo players with playing with Smurf. Also it was a great way to me to improve but thats gone too. What ways are good for self improvement in league.
4. What do you for in an champ which makes applicable for a nerf/buff. Is it what the players use on the champs or the kit itself. How do deal with champs on the edge of broken or useless?
