I must be playing a different game than you. Though i see fewer firebomb teams overall, i rarely have an issue choosing a non-dragon eye team (or any specific meta team i’d rather not deal with) from the 3 presented to me. Occasionally 2 of the teams are similar but rarely ever all 3. I don’t believe for a second this patch has been a failure and from this other thread i’d say a fair number of others would disagreed with your blanket “perception”.
Not everyone was happy with the change but more diversity than there was before seems to have been achieved according to many of the posters there.
