Ok.
Your guide is poor for so many reasons
1. It focuses on you telling which players to buy not how to play e.g - your team is based on speed. How do you heat a team same or faster than yours?
2. Your basis of spending crystals on refreshes for arena and hard nodes means you ultimately must build a base of crystals first. Until such a time 1/6 or 2/6 attemps is probably more realistic.shard drop rates are typically lower than what you have quoted for rey meaning time to farm will be significantly longer
3. In the first paragraph of your lv1-40 guide you are talking about FOTP and Rey - both hard to get if you are ftp and especially pre level 40. You are also quoting their maxed stats. A typical FOTP with a lv3 double tap has a 30% chance to attack again - not the 45% you have quoted
4. Your guide tells people to farm geonosian soldier, Poggle, luminara, ig-86, kylo ren, eeth koth, ventress , first order stormtrooper, poe, ig-88, hk47, resistance pilot, ewok elder, Darth sidious, rey, QGJ, barriss & Marketing dooku - so only 18 characters to farm and I've probably missed some out - I guess that's gotta be pretty easy right being f2p?
5. Gearing all of the above characters will also take a long time and considering all your energy is on farming shards it will take longer
6. You're assuming all servers are the same
7. I could carry on but that's enough for now
Now don't get me wrong - some of your guide would be useful to new players - however the main bulk isn't going to be much use
