I got an idea as a rare titan alternative. I don’t suggest against rare titan; I’m just wondering if this can appear alternatively with rare titan.
In certain stages of events and province stories, players gotta fight 2 or 3 bosses. It may be great to make it the same for titan.
For example, instead of 1 titan with 2 million HP, make it 2 titans (of course different color) with 1 million HP. It should still provide bonus chance for 4* AM, but if players fail to get it, at least they have added 2 titans to the chest (which doesn’t give extraordinary rewards either).
Just a thought.
