F2P Mini Rally Trap 300m might vs ~1B Leads Rallies & Solo 800m might army | Guild Expedition Action

F2P Mini Rally Trap 300m might vs 2 Mythic Leads Rallies till fall down & Solo 800m might batallion | Guild Expedition Action F2P Mini Rally Trap 300m might soloed one 800m might player's mix batallion with leader on keep in Guild Expedition and won by small margin while he was having 4 high level familiars and t5 and usually higher stats as being 800m might and mix war gears on. Discuss if you think it's a glitch/issue/error or possible. Then his guild came up to reclaim territory and started a rally, 2 rallies capped successfully from +-1B might players and gets burned in 3rd rally from Mythic player leading with 5 familiars, possibly he/she would have used army attack boost 50/70/100% as per the damage difference. Let me know if there is anything else... I am open to discuss
