I am a Russian speaker, so it is more convenient for me to use the old forms due to similar features. But not so old that English speakers themselves do not understand them at all. Plus, I am learning Slavic-Celtic languages, although official history and science do not recognize these languages as Slavic.
I have not come across such a word yet (thyne), apparently it is plural form of thy (your, sing.)? So far I know only about two variants of the word “thy” (your). “Thy” before a consonant of a next word and “thine” before a vowel.
Some offensive ultimates can be used for tanking. But some defenses ones are not capable of this, as with the Bunker, for example. Moreover, this ult is more a safe than a method of tanking. In the case of Muradin, thou can tank with the both his ults. The “fist” helps to isolate a dangerous enemy, save a teammate or thy self. Control is also a method of tanking. And the Avatar helps thou stay in action longer by blocking damage.
As for the Dark Swarm, it’s two in one: safe and zoning (also a tanking method) at the same time. Well, and of course the damage, that is, even 3 in one. However, with “Exchange” thou canst also get rid of one enemy for a while (sort of type of control), for example, from an enemy tank, save thy self, and cause damage.
P.s. By the way, I also do not like Falling Sword and Gourge. Because of the Falling Sword, the team is left without the tank for several seconds, and the Gourge, Stitches simply do not know when to use. Too often I witness of that how a Stitch suddenly running out into his backline at most unexpected moment to use a hook, leaving his team without the front, which often endeth sadly.
