if you play as a striker, or played against strikers, the obvious is pointed out, there freaking too hard to kill/or ur to freaking hard to kill. there the only one with damage bonus added. and extra speed. (<--totally essential). So if they don't want to decrease the strikers advantage, i propose adding more bonuses to the other classes.
Recon Class: smaller radius Disruption Field, change the guns speed bonus to gun damage bonus.
Guardian Class: bomb bonus should be the same as a recons, but with a bigger radius (not like gigantic radius but a little tad bigger )
Bombs: (FYI thts not a class, its a weapon xD) bombs are sucky in LD. unless u have modules, ur just a player stuck with a weapon tht doesnt do nothing. Many strikers Zoom right over them with no status-damage being dealt. WTF?! so....Bombs get better, ur run past it and game over. ur stuck (bombs like gravitons, electrons), elemental damge is dealt ("misty" bombs), or blasted away(blast, angry,etc bombs.) also i would like to see the bomb stay a little longer. ex) toxic bomb detonate for 6 seconds or something like tht.
as u saw, i didnt add alot of bonuses to the classes above or they will be the superior class in LD.
as a viewer and as MY critic, dont focus on any small flaws of wht i wrote, focus on the main idea (i know some of you like to point a mistake tht has nothing to do with the topic o.O) so, Should the Striker have an advantage over the other classes?
I'll agree with you in that Strikers can be a pain, but I've seen other classes work just as well. The point of LD is not to get kills (although that certainly helps), but to capture/hold points. A skilled Guardian should know how to help the team by knowing when to shield and when to attack. Similarly, a skilled Recon should know when to mark enemies and when to sneak past them to capture vulnerable points.
You said that Recons should have a smaller disruption field, and I'm honestly not sure how that's going to put them on-par with Strikers. I think if anything, their field should be larger so they can stay farther away from the opposing team while still marking them.
As for the Guardian class...While I'm not really opposed to giving them some bomb bonus, making it equal to Recon's bonus makes Recon almost useless. The purpose of a Recon is to infiltrate and support, and giving them a bomb advantage is an appropriate decision in my opinion.
As for bombs themselves, I've seen them used quite effectively in LD, especially Voltaic Tempest. A 5* bomb can completely cover a capture point, making it very difficult for the opposing team to capture. I've heard that Nitronomes are also extremely effective in LD because they basically block out everyone's vision for a bit. Lastly, with the Recon bonuses, it's hardly necessary to use bomb-related trinkets for bombs to be effective.
I don't know whether Strikers have too much of an advantage over the other classes, and I feel like with the right style of play you can deal with them appropriately. For me personally, I do find them to be annoying and hard to take out, but for that I blame a general lack of skill/coordination amongst me and my teammates.
