When fighting multiple threats, the optimal strategy is to kill them in descending order according to their "dangerousness : survivability" ratio, with the source of smallest ratio being dealt with as last. It can be easily proved that killing them in any other order yields a longer total execution time and consequently being exposed to more "danger" (e.g. damage).

Your strategy, Spikedshell, would lead to relatively low damage (most from and  ) and low utility (only slows from {{ai|Test of Spirit|Illaoi|E), {{ii|Dead Man's Plate|icononly=yes}} and {{ii|Iceborn Gauntlet|icononly=yes}}) for a total of mediocre overall "dangerousness". Your survivability'd be very high though, once again leading to an extremely low priority ratio, and thus your opponent'd just ignore you and kill as last champ (as your threat ratio'd still be probably higher than that of creeps). Because of that I didn't count {{ii|Thornmail|icononly=yes}} in, as neither its damage nor utility proc without being autoattacked.

However, if one replaces {{ii|Adaptive Helm|icononly=yes}}, {{ii|Spirit Visage|icononly=yes}} and {{ii|Thornmail|icononly=yes}} with more team-utility-focused items, it leads to lower survivability, but higher dangerousness, thus improving the priority ratio.

Lastly, one should also consider the amount of threat (utility or damage not scaling with {{as|AD}}) that can be provided by masteries and new runes. It just few days till we have old stat boosting runes removed after all. With sheer additional amount of utility that new runes offer, many builds that were formerly nigh impossible, could become feasible.
