Willbachbakal :

1 - about evasion : i will say it again it will only negate the BONUS DAMAGE from crits not the WHOLE ATTACK like jax's e or the old evasion ( i didnt know about the old evasion because i am kinda new to lol and even then i dont know why people keep mentioning it because it different from the new one ) so as a squishy ( the only class that will benefit from it just like adc are the only ones benefiting from crits ) you will end up taking the usual + 400 dmg attack not to mention other modifiers like draven's q or attack speed and that is still huge since you are not building tanky and you are a sitting duck once you use your spells because you lack in mobility and cant shrug off damage because you lack in sustain.

2 - about Last Whisper being the problem : you may think last whisper is the problem but the real problem is its abnormal syneregy with attack speed and crits added burst damage built usually by adc who also have good burst in their spells too and by toning it down you will be giving a big booty kick in da nutz to those ad based champs with no attack speed or crits like riven for example and i heared that riot is planning to change how %pen, reduction and flat pen works for all guys but didnt find anything about it.

3 - "With a crit chance of 50%, the chance of landing 3 crits in a row is 12.5%. With a PRD the chance would likely be lowered" ... that is true BUT ONLY when the PRD works on champion hits, because right now the PRD work on everything so just like i have said you can ABUSE the siege duration to score some normal autoes ( here is a tip for abusing : separate your attacks and dont use your full attack speed and count 3 or 4 normal separated hits ) and when fight start you can easily have 3 or 4 crits in a row thats why its necessary to make a separate PRD generator for BOTH crits and evasion ( my evasion doesnt need it because it only works on crits bonus damage so its on champion hits only ,,, hmm dont know if the wolves have crits as i remember something like that but not sure )
