Invoker is a hero ive been practising alot lately, but i havent really tried him out much in a proper game. he's an intimidating hero...
played a support pheonix game yesterday, havent really played him much and cringed when i rolled him for one of my compendium heroes, but i really enjoyed the game, hes an amazing team fight hero, and with a team that has good crowd control, he is just scary as.

looking at it now, DK have it in the bag. they still have a boot camp to go through and are probably slowing down to rest up for TI4, so i wouldnt let their performances concern you too much.
Empire and eG are too inconsistant, no way they could make it through the event without throwing. personally think fear is overated.
navi have gone into the past 2 TIs "off their game" and still managed to come 2nd, so I would never count them out. sure, last year they still managed to win a few tournaments befor TI3, but they were still dropping games agaisnt shit teams, throwing hard and struggling to keep up with the meta.
so i wouldnt count them out.
theyr all getting old now aswell, in terms of gamers, so they may consider retiring soon. their lack of adapting to the constant change in meta in the past 2 years has been showing, the meta is too controlling, limiting puppys unconventional picks
these stretch goals for the compendium are amazing btw, and the item drops and battle bonus is well worth the 10$ investment. dropped 10$ into points and got 15 load screens from it, cant wait for the immortal items etc.
