Hextech Annie

I feel the probability of unlocking hextech is super slim unless you spend a lot of money, but even then everything is still by chance. Is there going to be any type of indication as to an event in which the likelihood of getting_ rare gems_ will be more common? I feel with the fact that hextech is such a "luck" based skin that there should be a type of reward or challenge system that increases the chances or earns you a_ rare gem __such as getting at least a quadra kill or having a certain amount of kills before getting shut down. Things like these will not only persuade players to play their best but also get a reward in return likely to be of satisfaction to players. Also the quantity of _rare gems _required seems a bit much considering it takes multiple chances of _pure luck to acquire. Riot please let me know what you think of this.
