while I do agree redback could use tuning this thread should be dedicated to flea, thanks for your input
This kind of balancing is what I believe keeps adding to the constant imbalance between factories. Fleas being so disproportionally powerful is what gives the spider fac an edge in many current matchups. Instead of just removing the strong unit and making the factory weak, the strength between the different units should be normalized. Find the strongest unit and the weakest unit and exchange some of their strength. If the factory is generally a bit too oppressive you can nerf slightly more than you buff.
For example we've just had the amphibious bots, who relied mostly on Archers and Grizzlies, nerfed. Ducks, Buoys or Scallops were rarely used, and by simply nerfing Archer and not buffing one of those underused units, the result is that hardly anyone starts Amphib anymore. (Although I don't believe more than a 2% buff would've been needed)
This is by far not the first time for this to happen and I'm just unsure whether the intention of every discussion of a single unit is really intended to nerf/buff an entire factory. Because if that's not your intention, you'll have to include some other unit in the spider lineup to compensate.
To get to the point of this thread, I do believe Fleas need a slight
range or dps decrease. Keeping the longer range does make for more interesting swarm strategies. I also believe that Redbacks, Venoms and Hermits are generally underperforming.
