@Meddler: What are you trying with Irelia in PBE?
#Irelia Ionian Fervor (Passive) - [several changes! WIP] Range down to 1000 from 1400 No longer reduces duration of disables for each nearby enemy champion 1=10%, 2=25%, 3= 40%. Now reduces duration of disables on Irelia based on if she is outnumbered (self + allies vs enemies)
- Even Fight is always 10%
- Outnumber bonus is 25/30/35/40% at levels 1/6/11/16 [EXAMPLES:
- Irelia and her jungler are ganking a single enemy. Irelia gets 0%.
- Irelia is dueling a renekton in lane. Irelia gets 10%
- Irelia is being ganked by Lee sin and Renekton - Irelia gets 25-40% based on level.]
Sounds like you're adjusting Irelia to be the "stronger when at a disadvantage" Champion, changing her passive so she doesn't ALWAYS have 40% bonus Tenacity for team fights, but only that bonus when her team is caught out of position. It's a novel concept, but I can only see this as a band-aid fix for the majority of other issues she has (namely, too many things in her kit).
I hope that this is only to tide her by until she's scheduled for a full rework, not the extent of the rework itself.
