Is there a shortcut for typing ascension tier and ascension level? What about class nodes?

As suggested by many others including @Kerridoc and @Dante2377, Short is best for the new class update.

8/8 5* 4.80 +1 hero ( 8/8 special skill, 5 Star, Tier 4, level 80, 1 class node ) is redundant because 8/8 5* 4.80 is needed to get 8/8 5* 4.80+1 hero.

I like 5*+1 hero ( 5 star, 1 class node ). But I have seen 5+1 hero also used. While slightly more confusing, 5+1 hero also works.
