Balance Development Log #1 - Void Rogue(v0.21)

Void Rogue could have 3 playstyles:
Tanky AoE-sustained bruiser. (str)
Glass cannonish agility carry. (agi)
Bursty magical assassin. (int)

This is how it ideally would be. However, currently the skills are messed up.
Lethal poison gives damage over time for agility. This doesn't fit with the agility carry playstyle, as usually a carry has to kill the target too fast for the poison to be useful. This should be changed to str, since tanks have the most time to use the poisons.

Null Blade gives cheap magical damage based on intelligence. This doesn't fit with the magical assassin playstyle, because intelligence-based playstyles should be mana-hungry and bursty. However, this is not a problem, as it doesn't appear to create any balance issues and fills in nicely to give extra activity and lessen the incredible weakness to swarms of units.
In its current state Null Blade isn't completed yet (it doesn't return). To compensate for this the damage rate is doubled. It will likely be more powerful for tanky builds later on, due to the poison being applied twice.
Agility builds can use this in conjunction with poisons, albeit for less gain.

Nether Walk is a bursty ambush/escape spell that fits perfectly by design. The only issue might be that the burst damage is so high that engaging with it is too safe (dead enemies aren't dangerous).

Void Rage currently gives damage for strength, attack rate for agility and BnV range for intelligence. I don't like the skill as it is, because it is straightforward damage without any downsides for the str+agi builds.
I would prefer to switch around the str and agi bonuses, because str builds generally have lower attack speed, but rely more on reapplying poisons. Agility builds then again need the damage to stay the glasscannons they are while attack rate is something they have lots of anyway.

Condemn is a high damage single-target nuke that heals the caster. It works as intended and probably isn't too powerful, because it has a high mana cost and relatively high cooldown.

There is also the problem that lategame Void Rogue essentially has the benefits of all builds, due to high stat gains from levelling.

tl;dr

Lethal Poison:
Damage based on agi > damage based on str.

Nether Walk:
Damage ratio 5 > 3.5 (experimental)

Void Rage:
Attack rate scaled by agi > str
Damage scaled by str > agi
BnV range scaled by int > unchanged

Stat gains from levelling 1.2 > 0.9 (experimental)
