Thanks for taking your time to read this!
In light of the recent outcry about players being unable to draw event units, I would like to suggest that the event unit be a guaranteed drop with every 400 gems pull (heck, I'll be happy even if it's 1 guaranteed event unit drop with every 20x pulls).
My rationale for the above is because players are generally summoning during events because they want to have a better chance to be competing on equal footing with the rest. Personally, I have enough Cybella/Luthor/Teresa/Vincent/Zedd to make level 40s for every job they have. I'm pretty sure some players are in my shoes and the acquisition of any of those units with 5* potential is essentially getting a pixie with no guaranteed faith.
Instead of just letting RNG take its brutal course, lets instill some certainty for everyone and give everyone a fair chance at taking part in the event.
Hope the developers are able to take my proposal into consideration.
