The previous few event heroes has been relatively easy for even new players to obtain, because 100% completion of the event wasn't that hard at all as long as one spends their daily allotted energy on the event itself. Previous events only required completion of 12 trials to count towards the 100% chest containing the event hero, so why is there a need to increase the number of trials needed to 15 now? This wouldn't be so bad on it's own, but coupled with the ridiculous requirement for Trial 2 in Legendary difficulty, this makes it extremely hard for the average player to complete the 15 trials needed to obtain the 100% chest. And because I've seen no other threads on the forum talking about this issue, I can only assume that most other players are okay with this artificial increase in difficulty?
My thoughts about this matter aside, I'd like to preferably obtain the 100% completion chest without spending an exorbitant amount of cash and gems on hero summoning, so I'd appreciate it if someone who has managed to complete that trial in question share their team composition(s). Thanks.
