Simplest/easiest TH10 War Attack for 2 Stars
I'm looking for some advice to pass along to a fellow clanmate who is having trouble with war attacks. For context, we are a fairly competitive war clan comprised of about 50% TH9s, 40% TH8s, 5% TH7s, and 5% (2-3) TH10s.
One of our TH10s is a 60 year-old guy (let's call him "Bob") that plays CoC on a smartphone screen, has somewhat poor eyesight, and has a low ability to learn advanced attack strats. Bob is extremely enthusiastic when it comes to war, great for morale, donates a ton of troops, and just a really nice guy who thoroughly enjoys being part of the clan, particularly the comradarie of warring together.
The problem we have is that Bob has a very tough time executing any remotely challenging attack strategy, even a relatively simple attack like GoWiPe. We're structured such that we only really need him to 1-2 star a TH10 and 2star one of their top TH9s, but even this is difficult to accomplish. His main struggles are 1) keeping track of a large number of different troop (loses track of them on a small screen) , 2) remembering the appropriate timing & order for troop deployment, 3) switching back and forth across different units on the troop bar, and 4) spell timing & placement.
Does anyone have any suggestions I can use to coach Bob into consistently attaining 2stars on TH9s and 1-2 stars on TH10s?
I'm looking mainly for a low number of district troop types and spells, straightforward deployment with a low level of variability, and infrequent need for improvised attack decisions. In the past, Bob has preferred mass drags because all units can be deployed early in the attack and there is only one troop type, but obviously this attack strat is not really viable above TH8.
Thanks for any advice in advance!
