http://haydenmoses.livedoor.blog/archives/15126798.html Thermite and Hibana are widely considered the bedrock of a good team composition. They're the two main hard breachers in Siege and their ability to breach reinforced walls is one of Siege's fundamental mechanics. A round of Siege is often won or lost based on how much of the defense the attackers were able to tear down http://jeffbenedict.pixnet.net/blog/post/270846064-the-six-regions-of-the-fallout-76-map and these two cut the deepest. If you're looking to give your team the best chance in most situations take one or both.
Shorter round times stand out as the single most important change from Casual. One minute might not seem like that much at first but after a few attacking rounds you'll no doubt find yourself with 20 seconds left and nowhere near the objective yet. That missing minute means that you can't waste any moment while attacking. Droning an entire floor is nice but using up that time is a big commitment. Be efficient with your droning and always be making moves towards the objective.
Calls for a second Operation Health have been happening on occasion for the better part of a year http://aldrich.blog.wox.cc/entry3.html but a quick scroll through Reddit shows they've grown much more prolific over the past month or so. Some want balance changes after all Lord Tachanka is still Lord Tachanka some want bug fixes and some want further protections against cheating.
Basically Rainbow Six Siege players are making it so when the other team looks at a certain spot on their team's bombsite their vision become bugged https://www.givology.org/~LucyPartridge/blog/658082/ and the textures in their game start flying off in wild directions. This makes it basically impossible for the opposing team to see anything. Players have been cagey about explaining how exactly the glitch works for fear of it becoming more common but it's already spreading on the internet.
Those who do know how precisely the exploit works are keeping quiet for fear of it getting around too much. Except for the bad people who are abusing it and telling others how to abuse it. In short if you look at a particular spot in the level http://fredericevelina.classtell.com/fredericevelina/arcanelegendsdoesanexcellentjobofmanagingtheworld your view will become filled with stretched polygons swirling around and blocking your view. Oh you can look away but it'll be too late your virtual eyes will be gummed up with trash for the rest of the game.
Additionally players reported another exploit which glitches the screen. As seen in dankamushy video on Reddit attacking team was running towards the objective when all of a sudden weird graphical artefacts appeared on the screen for the whole team making them easy prey for defenders.
Sledge and Buck are two sides of the same coin both accomplishing the same goal in different ways. They both excel at soft breaching: Sledge with his titular hammer https://neolatino.ning.com/profiles/blogs/toram-online-stage-event-held-at-the-asobimo-booth and Buck with his rifle-mounted shotgun. They're both two-speed ops and both carry frag grenades so the choice between them really comes down to the preference between Buck's unmatched breaching speed and Sledge's versatility. http://thomaswodehous.bloger.co.il/291285/
