These days it seems like you need to farm a linkens or a silver edge or an mkb, to give a few examples, every game. I suggest making a lesser form a pickable skill.
New skills or augments of old skills:
Gravekeepers Cloak: (add to existing) The first layer (untouched) will have a 100% spell block for any non-ultimate spell. The cd will be 60/50/40/30. Scepter Upgradable: can block ultimate spells (as long as the first layer is still intact).
Trueshot Aura (aka Precision Aura): remove the active component and replace it with true shot precision. Add to existing skill: 10/15/20/25% more likely to hit the target. A level 4 true shot aura will subtract 25% from the evasion of the target. Blur for example will be cut to 25%.
Shadow Walk (BH's ww): remove the damage bonuses (30/60/90/120). Add: disable their passive abilities, and reduce their damage output by 20/30/40/50% for 5 seconds.
Interested in hearing the community's response to these proposals.
