Competitive viability? Meh! ¯\_(ツ)_/¯
Strong meh.
This is too gimmicky/situational for competitive use. Jumping around wildly, while entertaining, will not prove useful consistently in any match, and you'd also be using every slot to make a set like that, depriving you of far more useful abilities.
Stacking Sub Up on one piece of gear if you're using beacons would be more useful in competitive.
If you want to form a scenario where this set up works, you must consider the following:
- Can I count on a teammate to either be available for a safe jump point at any moment midcombat, or set up safe beacons at prediscussed map points? If so, how are we prepared to start the match, and how do we solidify these safe jump points? If multiple teammates are trying to create quick jump points for you, how does this affect interaction with enemies during combat?
- What maps allow this strategy to flourish best, and what are desirable points to look toward jumping to on each map? Combat heavy zones for surprise engagement to create an advantage in number by surprise splats? A constant support position that is very rarely absent from the field, keeping key turf under your control? Jumping to and assisting in pushing objective relentlessly, even under enemy blockade?
- What weapons would you be locked into if considering an offensive (most likely) use of this tactic? What weapons would best provide a support role (less likely) for this tactic? This seems like you'd really want to count on something like the Dynamo or Splash-o-matic in either case.
I would consider this only as a fun gimmicky set up, but hear this out:
Dynamo Roller for support jumps
or
Krak-on Roller for quick jumps to beacon placement
combined with another quick super jump stack on Splash-o-matic, a Rapid Blaster or Custom Blaster for coverage +jump point, and a T-Tek for defensive/offensive shift depending on tide of match. This covers most of your bases for this tactic, though you're kind of out of luck if a good sniper is on the other team.
