What happened to 4.4 beta?

It seems that 4.4 beta has been tested for so many times and it's pretty much finalized... While that's the case, I do think the map itself has some fundamental problems. Such as:

- Does Tax/Upkeep justify the balance of Cat force (a single player) and Mice force (a team of players)?
- How many times have you seen cats use the following listed spells on Mice:
1. Area No Shield / Mana
2. Meltdown
3. Lock Mice
4. Sunken (Mouse Trap)
- How many games you play in Jungle without seeing a Mice get massive Cannons at late game and wall himself in a base, and continuously restoring the base's minerals?
- How many times have Mice players use massive Zerglings (Stupid Devin) against Cat?
- How many times have Mice use tons and tons of Stargate (Hard Cheese) for defensive and offensive (ie: trap cat)?
- How many times have you seen Infested Terrans blow up upon spawning at middle because a Mice player purposely put a Zergling there in advance?

To address the above questions, I completely give up Tax/Upkeep and plan to "correct" the above-mentioned problem in terms of game play in a new version - Jungle 5.0.
