Arc Warden suggestions

[leanjiji]

Hi folks.

There are a few things I would like to suggest for this hero.

7.34d - Tempest double can now be casted on self (double click), when arc warden is moving towards a direction and double clicked on ult is performed, the hero actually does a 180 degrees (looking backwards) before performing the ult. Can this be changed to casted with the current facing angle instead? Because this might give a huge clunkiness on double clicking the ult.

Magnetic field shard
Current - 30% slow and 40% magic resistance
Suggestion #1 - (Slight change) Allow this bubble knockback the enemy by certain range when entering the bubble for the first time (instead of during bubble spawn time) while keeping the current benefits of slow and magic resistance.
Suggestion #2 - (Rework) Magnetic field now has 2 seconds duration(or full duration if that is not broken) that prevents enemy from entering the bubble and will constantly knockback enemies that tries to enter it.
Suggestion #3 - (Rework) Allows Tempest Double to share the same visual aspect as the main hero (not darker color) until any enemy hero is within a certain range (700 range maybe?)
**this third suggestion can be placed within anywhere else for a talent at level 25 or Aghanim scepter

That'd be all, thanks for reading.
