Ronin is love, Ronin is life.
Your experience mostly comming from large format teams games, well its no surprise that Ronin seems like a waste, the sentiment of "arty wrecks" goes for every factory in lobsterpot. In small format and 1v1s tho? Ronin is a god damn beast.
You get:
> A fast all-terrain bot which is dirt-cheap and can be everywhere your opponents attention is not;
> Skirmisher which you can mass before some facs make even one;
> Probably one the best units to get a unified stretched line-like frontline;
> A unit just as capable of raiding as
anything cloaky Glaive, especially after you force an instinctive response of "through Lotus/Picket everywhere";
[Spoiler]Where a Glaive fails, a Ronin succeeds
> In team-games, if you manage to dictate a fast enough tempo, Ronin can suddenly become the best skirmisher.
Hell, my understanding that the thing was so good it got debuff for *literally firing its weapon*. But now its gone, and the kite-king is back at it again.
Sling is easier to use and understand, and will get the job done. Ronin will cost you some micro and proficiency, but it'll get it done faster and is much more versatile.
