I never was very skilled when it comes to judging if someone is trolling or just not very good to form a coherent opinion.
The 800k hours played on WHC, the chad talk, and the paragraph about the treatment and evaluation of engis makes me wonder which one it is in this case.
Anyway, presuming you just wrote this sleepdrunk at 4am. I dont get the hate for Jav, unless you talk about sub cata difficulties. The reason its not worth talking about Legend, or even champ, is that hero power isnt a given. If you end up with 650 power in champ, for whatever reason, weapons are all op. Krubers bloody repeater can onhit specials there and wont ever run out of ammo, because of the not existing special density. When talking about balancing for Legend, I can already see the vault farmers having bloodfoam coming out of their mouth, eyes, and ears.
On cata the only silly part about Javs is the massive cleave. About four times as much as handgun is a just a tiny tad bit much. If its supposed to be elgis shotgun, we need some different changes. For an elgi weapon it also needs a surprising amount of properties to headshot kill special(, which is more than zero).
If you take Elgis Longbow as benchmark, which needs no breakpoints to kill cata specials with a headshot, has no funny arch you need to come to terms with, and enough of a max ammo size to not run out unless you start shooting thick air, jav is fine if, again, the cleave values get fixed. (Btw. Thumbs up for making me look like Iam fine with a sniping weapon with low to no reaload is fine to not need breakpoints for killing cata specials to the head. Hint: Its absolutely not.)
Moonfires silly breakpoints, Waystalkers wavedelete=true volley, and SoTT are a much bigger problem atm, than Jav ever was.
About the last paragraph. Thats kind of the point of this thread. FK turns into a range career with extras when armed with a Nuclear Bow. When a weapon does something like that, without the help of passives and Talents, something is wrong. I couldn’t say jav does the same.
