Some Ideas/Recommendations
Just a few ideas from a casual League player that may make some summoners' day a little bit better.
1. Make secondary roles optional in draft mode. A lot of people dislike the fact that they "always get their secondary" when playing draft mode. This could be easily avoided if summoners had an option to only select a primary role, placing them in a lower-priority queue. To many, this will be better than selecting a secondary role they may not like; better to wait longer for a role you'll enjoy than get your secondary and scramble to trade.
2. Allow players to manually trade roles. We all know there've been complaints about the "time wasting" pick intent phase in draft mode, and there have also been instances in which players want to trade roles, which is sometimes a hassle. Both of these problems could be solved if there was a slightly longer pick intent phase, during which players can request to trade roles with another summoner, just as one would trade champions.
3. Add new status messages in the friends bar. We've probably all had that time when we've queued up in solo and joined champion select when a friend suddenly logs on and asks if you want to play, forcing you to choose between dodging or ignoring your pal. While the mobile app offers a solution to this problem in some cases, not everyone has a mobile phone, and it's sometimes quicker just to log in. In such a case, it might make lives easier to add more messages that appear in the Friends tab, for instance, "Launching" or "Logging In".
I also have some ideas for possible game modes which some people may enjoy playing:
1. Role Specific Modes. I'm sure a lot of us enjoyed watching the best players duke it out in the Marksman and Assassin Modes at All Stars, so why not add something like for the people to try? I'm sure it would make for some interesting team compositions and strategies, as well as fun for the players.
2. Randomized Abilities and Sprites. I've always pondered what a Teemo would look like using an Alistar Q into a Yasuo ulti. We might possibly see this in a game mode where a champion's sprite and abilities are completely randomized. I'm not sure how this would work in terms of pick phase or how randomization would exactly work, but I think it could be a hilarious game mode which could make for some intriguing clips to someone's highlight reel.
3. Champion Test Run Simulator. This isn't a "seasonal game mode", but I think this is needed. We all enjoy trying out new champions, but sometimes it's difficult to wait on the rift until maximum level and 10k gold or so to see a champion's full potential (or the alternative: running blindly into a match not knowing what to do). It would be nice if a sandbox-esque game mode where a player can test any owned or free rotation champion at any level with any items would be nice against any enemy.
Thank you for taking the time to read through my recommendations. I hope that maybe some of these ideas can be incorporated into the game, and if not, I hope you at least enjoyed seeing my ideas. I'm glad to be a part of the League of Legends community, and I hope that we, together, can make the game more enjoyable for the players.
