First have a minimum participation 200 banners defence and similar on offence. Anyone under this has way too much left on the bench.
Then structure defence according to match up, hard work for a TW officer but if your TW officer believes in sandbagging it’s over before it starts as everyone needs to show up believing it’s worth the effort. I have seen this when I was an officer in a previous guild, our TW officer claimed it sandbagging and disappeared for the duration so hardly anyone showed up. We lost due to activity, our opposition barely made it through our defences but was top late to rally the guild.
Morgoth had a good suggestion. If you have 50 teams with limited counter or just one good counter and they only have 35 players put them all down with similar teams requiring the same counter to exhaust there options and eek out their GL’s on teams that don’t really need it.
Datacrons limit counters so you should be going for appropriate datacrons on def and off. The first 3 zones should all have high level datacrons.
Have the guild comfortable with off-meta counters and knowledgeable on all counter's for typical defences. Some of my guilds had discord tabs for go to counters to help players stretch their rosters and clear walls quickly and efficiently.
Some times it works to have dummy walls up front, fairly strong but not as strong as the zones behind. A guild who ‘thinks’ you are weaker may try to go through both sides and get stuck.
Focus down one side so you get to the back wall as it’s worth more points and TW zones are usually front heavy.
If you get stuck in a wall… experiment so you figure out something that works next time. If you see gaps raise it to the guild to see if anyone wants to work investing into their plans. For example ships is a a weak spot for a lot of 300M guilds. But if some players focus on learning off meta counters or unlocking more Levi’s then it can boost holds or speed up clearing zones.
Invest in TW omicrons that are impactful. Fulcrum can rip apart starkiller walls even with its current datacron. Geo’s and Sep can be annoying back walls with their omicron and a decent datacron.
I am not opposed to them looking at the matchup algorithm again, as I agree more often than not the match up is wonky, but in a 580M guild with optional participation we have just as many when we are out matched as we out match. We have a healthy win rate because we have been successful against some bigger guilds. That is why I strongly oppose it being sandbagging.
I have been in 300M guilds pushing for 50 members for droid brains it is painful. More so I know the issue to recruit and get 50 active members who are available every TW. Since there are other ways to earn droid brains, I would rather go for activity over forcing everyone to sign up any day. The larger guilds will certainly not alter this until there’s better reward tiers to chase at least above the 380M.
