I would like to suggest to at least double the dmg of the Sudaruska charge attack or increase the AoE significantly.

The sword looks really cool, but it totally sucks compared to not just the best, but a whole lot of other swords, not just in specific, but in many situations.

Edit: btw, the slow walking speed during charge and the slow swings DO symbolize the virtual weight of the sword, however striking with such a weight should logically be alot more devastating compared to other swords, which do not have any drawbacks of weighing much

E2: thers a similar issue, that has been up for longer time with the big angry bomb
