DotA Allstars 6.54

Just a few weeks ago Icefrog released 6.53, and while I expect 6.53b to be released soon after, instead they went straight to DotA Allstars 6.54 with various new addition/alteration. As usual the map can be downloaded from getdota.
The changelog to be noted:

-Rebalanced Invoker. He can now use invoke at level two (meaning, take either Quas, Wex or Exort at lvl 1 and made a pure element spell at lvl 2). And there's various manacost/cooldown changes, which I do think made him a little more useful early games (since he don't have to wait till level 5 to gank).

-Reworked Shadow Priest. Same model, but no more fast resurrection+no money lose when dying. His Grave changed completely into a targetable avatar (except that it completely nullify any damage for 5 seconds). Weave become an ultimate, where both allies and enemies within 600 AOE will be affected with armor increase/decrease. And extra bounce for Wave at level 3 and 4. Will he become as useful as he once was? Maybe he's still good at supporting, but now he's not reliable to support carry heroes anymore (in term of grave).

-Phantom Lancer got virtually nerfed. Spirit Lance damage decreased (250 instead of the old 310 damage) but also decreased cooldown, plus progressively higher manacost.
Doppelwalk invis decreased from 12 to 8 seconds, his images now takes 400% damages more, while his maximum images count decreased from 8 to 4. This is just...wow imo the biggest neft PL ever had. The rest of the nerf is okay imo, but decreasing his number of images will reduced his efficiency as late carry.

-Changes to Abaddon' Apothic Shield and Borrowed Time. Borrowed Time cooldown increased to 60 seconds. Apothic Shield is even more interesting, with 15 seconds duration and 9 seconds cooldown at level 4, with less damage tankability (175 instead of 275). While the damage absorbed is decreased, his role as life saver is definitely increased with such short cooldown (plus can Shield two allies at one time).

-Rylai Crestfall ultimate mechanic altered a bit. Instead of the slow coming from the explosion, now it came from the field itself. About the whole mechanic, I'm still nto sure whether it is a randomly triggered explosion or a simultaneous AOE nuke. Need more information on this.
-many visual effect changes, some are interesting, while others are weird. Queen of Pain Sonic Wave turned into a weird circular wave (make sense though, it's "sonic" after all). Freezing Field, Blackhole, Weave, Spirit Lance, Meledict, and even Flask of Sapphire Water is changed.

-mode -mi is added for miniheroes. LOOOOL chibi-heroes ftw :3
