Warrior gives 60 AD + 10% CDR, while Runic Echoes gives 60 AP + 7% MS + Echo Passive. Warrior is 145% gold efficient and Runic Echoes is 97% gold efficient (without its passive). The Echo passive gives a bonus 60 + 10% AP magic damage after 100 charges - for the passive to make Runic Echoes have the same gold efficiency as Warrior, it would need to be worth 785 gold. Is it really worth that amount though? Thoughts?
because it was on par with melee champs when it gave 80 + 10% but Riot likes to put mages in a bad spot at all points of the game.
so champs like : 
make the LC$ plays.
Its kind of like when they semi-gutted 
because she was doing better than Lee $in.
they took away a bunch of her power, gutted echoes and never returned her champion debuffs.
but its okay, will never ever see nerfs and will always be the most valuable jungler.
You are greatly underestimating the value of the Echo passive and the importance of movement speed for junglers.
Don't forget that:
Movement speed is difficult to determine a gold value for.
Even a slight difference in movement speed can be enough to let you catch/escape enemy champions, avoid skillshots, or reach a skirmish several seconds sooner.
I think they need to add 2 ap items, lichbane jungler item or nashor's tooth type ap jungler item with echo jungler item? Maybe even a mini zhonyas item for jungle!
Warrior still gives cdr .Also ap champs are forced to buy echo warrior type champs can buy blood razor cinder or warrior .
